09a9b629ee feat(chat): add You.com web search provider (#18478)
### Summary

Adds You.com as a built-in Web Search provider for RAGFlow Chat,
alongside Tavily and Querit, using the provider-neutral dispatch #17813
put in place. No changes to existing Tavily or Querit behaviour.

You.com runs its own web index and returns several extracted passages
per result rather than a single meta description, so retrieved chunks
arrive with usable context.

ab40c90118 fix: avoid quadratic dedup in RAG merge paths (#18135)
## Summary
Fixes #18025. Both merge paths deduplicated IDs by scanning a plain list
(`item not in list`) inside a loop while appending — O(n²) per merge.
Replaced with a set-backed `seen` check alongside the existing ordered
list: same order, same dedup result, O(n).

86c520a336 fix(nlp): differentiate alphabetic OOV term weights (#18470)
### Summary

Closes #18414.

`rag/res/term.freq` is not shipped, and both term-weight implementations
therefore assigned the same `300` fallback frequency to every lowercase
Latin token. With no tokenizer frequency, NER, or POS signal, function
words and content words received identical lexical boosts.

This PR adds the same bounded out-of-vocabulary prior to Python and Go:

- Use it only when the explicit DF dictionary or tokenizer has no
frequency.
- Count Latin, Greek, and Cyrillic letters, including uppercase and
accented forms.
- Keep the existing frequency of `300` for words up to three letters,
halve it every two additional letters, and clamp it at `10`.
- Reject digits, underscores, and logographic terms so Chinese and other
existing fine-grained-tokenizer paths are unchanged.
- Treat an absent optional `term.freq` as the supported fallback path
without a startup warning, while still logging inaccessible or malformed
dictionaries.

A corpus-derived table was intentionally not added: that would require
provenance/licensing decisions, language detection, and handling
cross-language homographs. The bounded prior is deterministic,
dependency-free, and fixes the equal-weight degradation for
whitespace-delimited alphabetic languages without claiming
corpus-specific precision.

Python and Go consume one shared fixture covering ASCII, uppercase,
accented Latin, Greek, Cyrillic, separators, invalid mixed tokens, and a
CJK non-match. Both sides also verify the issue's ordering (`was <
largest < supplier < equipment`) and that an explicit dictionary entry
still takes precedence.

f1e6b22c4b fix: honor minimum_should_match in GaussDB search (#18456)
### Summary

GaussDB DocEngine could return no chunks for conversational queries even
when relevant content was available. `Dealer.search()` supplies
`minimum_should_match` (30%, then 10% on retry), but the GaussDB adapter
discarded it and built a single `plainto_tsquery` from every token. This
effectively required all conversational filler terms to match.

add00924e7 fix: replace editdistance with rapidfuzz for python 3.13 wheel support (#18132)
### Summary

Fixes #18107.

`editdistance==0.8.1` (the only recent release on PyPI) has no cp313
wheels for any platform. Since this project requires exactly Python
3.13, `uv`/`pip`/`poetry` fall back to building it from source (Cython),
which fails on Windows for anyone without a working C build toolchain —
that's the PEP 517 build error in the issue.

Swapped `editdistance` for `rapidfuzz`, which ships full cp313 wheels
(win32/win_amd64/win_arm64 included) and has no build-from-source step
on any of our target platforms. The only call site was
`EntityResolution.is_similarity` in `rag/graphrag/entity_resolution.py`,
using `editdistance.eval(a, b)` to get the unweighted Levenshtein
distance between two entity names.
`rapidfuzz.distance.Levenshtein.distance(a, b)` computes the same thing
(verified identical output on several string pairs) and is used as a
direct replacement.

### Summary

Refs #17885.

Mistral figure enrichment now receives the dataset language through the
production parsing path. `by_mistral_ocr` forwards `lang` to
`MistralParser.parse_pdf`; the parser stores the normalized language and
passes it to the figure-description prompt. Empty or missing values
still fall back to English.

0cfd8f41e4 fix: improve incremental wiki compilation (#18130)
### What problem does this PR solve?

Incremental Wiki compilation could lose provenance for claim-light
entities, produce unstable page groups across embedding models, route
entities to unrelated pages, and assign topics without sufficient
page-level context. Document removals and page membership changes could
also leave stale Wiki state.

This PR:

- preserves source document and chunk provenance throughout entity
matching, reduction, page generation, and deletion;
- uses embeddings to retrieve candidates and the LLM to make final page
grouping and incremental routing decisions;
- batches embedding and LLM operations with bounded concurrency and
deterministic fallbacks;
- selects source-scoped topic candidates with embeddings before the page
LLM chooses the final topic;
- rebuilds Wiki state when the compilation mode or embedding model
changes;
- normalizes Wiki array fields returned by the API and retains entities
without relations in graph responses.

9b05e5c67e Fix: delimiter is chunk boundary, drop token_size atom-split (OVER_CAP default) (#17808)
## Summary

Fixes a regression introduced by #17203 (strict-cap atom-split) and a
secondary delimiter-handling bug from #17723.

**Root cause:**
- #17203 added `_split_oversized_unit` / `_compute_chunk_update`, which
split oversize units into ≤ token_size pieces. This collapsed
`token_size=1` into 1-token chunks and set the cap at 512, mismatching
the model-layer truncation boundary (embedding ~8191 / rerank
500/4096/8192/2048). Atom-split is unnecessary: oversize units stay
whole and the model layer truncates.
- #17723's delimiter handling dropped consecutive delimiters (`A####B`
-> `A##B`), glued JSON items with `"".join`, ignored
`children_delimiters`, and stripped whitespace delimiters.

## Changes

- New pure helper `merge_paragraphs(paragraphs, token_size, strategy)`
with a `MergeStrategy` enum (`UNDER_CAP` / `OVER_CAP`); **default
`OVER_CAP`**. `UNDER_CAP` is a strict cap (never overflows
`token_size`); `OVER_CAP` greedily accumulates adjacent paragraphs while
the projected total stays within `token_size`, merging one
boundary-overflow paragraph before closing. Oversize paragraphs stand
alone.
- `naive_merge` / `naive_merge_with_images` /
`RAGFlowTxtParser.parser_txt` now use `merge_paragraphs`; atom-split
removed. `naive_merge` / `naive_merge_with_images` always split a
section on the delimiter whenever one is present (even when the section
already fits `token_size`), so delimiter text never leaks into a chunk.
Only the empty-delimiter (size-only) mode skips splitting.
- `token_chunker`: delimiter text is dropped (not stripped); JSON flush
joins buffered items with `"\n"`; `children_delimiters` and
`PDF_POSITIONS_KEY` are preserved on the delimiter path. PDF positions
are now attributed **per segment** — each split chunk carries only the
positions of the item(s) that contributed to it — fixing a leak where
page-N coordinates were attached to page-M chunks and all segments
shared one preview image.
- `test_txt_parser.py` rewritten to assert the new contract (not the old
strict cap); `naive_merge` and delimiter-case-sensitive matrices
updated.

## Contract (refs #17799)

- user specified delimiter = chunk boundary; user specified delimiter
text never enters a chunk.
- `token_size` = soft target + merge strategy; no atom-split.
- Default strategy = `OVER_CAP`; migration can switch to `UNDER_CAP`
(strict cap).
- `OVER_CAP` has no hard cap; the model layer truncates oversize units.
`UNDER_CAP` enforces a strict cap.

## Notes

- Closes the wrong-object revert in #17774 (revert #17723 would
re-introduce delimiter-in-chunk and the strict cap).
- Go-side alignment (`internal/ingestion/component/chunker/token.go`) is
a follow-up PR.

166758cb0f fix: migrate mistralai to 2.x and remediate CVE-2025-67221 (orjson) (#17810)
## Summary
  
Migrates `mistralai` from `==0.4.2` to `>=2.7.2,<3.0.0` to unblock the
orjson CVE fix. The old SDK pinned `orjson>=3.9.10,<3.11`, preventing
upgrade to the patched version.
  
  | CVE | Severity | Package | Installed | Fixed in |
  |---|---|---|---|---|
  | CVE-2025-67221 | HIGH | orjson | 3.10.18 | 3.11.6 |

`mistralai` 2.x (the current maintained version) drops the orjson
dependency entirely. Added `orjson>=3.11.6` to `constraint-dependencies`
to pin the floor for remaining parent packages (`langgraph-sdk`,
`langsmith`, `ranx`).

197b142cef feat(serenedb): add SereneDB doc-store engine (Go + Python connectors) (#17375)
## What

Adds [**SereneDB**](https://serenedb.com) as a selectable doc-store
engine on **both** RAGFlow paths:
- the **Go** `DocEngine` (`internal/engine/serenedb`), alongside
Elasticsearch and Infinity;
- the **Python** `DocStoreConnection` (`rag/utils/serenedb_conn.py`) +
`DOC_ENGINE=serenedb` registration.

SereneDB is a PostgreSQL-wire engine (DuckDB execution) whose single
inverted index carries **both** a scored text column (`@@`, BM25) and an
IVF vector column (`<#>`, inner product), so hybrid search is one SQL
statement. The Go engine connects with `database/sql` + `lib/pq`
(already a dependency, no new module); the Python connector uses
psycopg2 (already a dependency).

## Storage model

One table per tenant with `kb_id` as a filter column - the
**Elasticsearch / OceanBase** model, not Infinity's per-dataset tables.
This keeps BM25 statistics (IDF, avgdl) computed over the whole tenant
corpus (global IDF). Both connectors use this identical layout, so they
are storage- and retrieval-compatible: `hybrid` proxy routing and
Python↔Go switching are safe. On the Python side the connector is wired
as OceanBase's plain-SQL sibling (chunk_data JSON metadata, inline chunk
vectors, verbatim ES field names); the ES tokenizer path is unchanged.
Metadata stays one table per tenant (`ragflow_doc_meta_<tenant>`).

The query shapes mirror the Python connector, including the five
empirically-found landmines: the scored dictionary needs `frequency +
norm` (else `BM25()` silently returns 0.0), the `@@` query is the
tokenized query, the scored lexical branch matches one column, vectors
use an L2-normalized shadow column with `ip`/`sq8`, and the similarity
threshold goes directly in the ANN scan's `WHERE`. **Minimum engine
version: SereneDB 26.07.4.**

d4ceeee4ed refactor(nlp): collapse 6 delimiter-parser implementations into one canonical helper (#17383) (#17387)
## Summary

Six sites used to read the same `parser_config.delimiter` field with
divergent grammars:

- `rag.nlp.get_delimiters` (PDF/DOCX/HTML/EPUB/JSON/CSV/XLSX/email/book)
- `rag.nlp.naive_merge` (custom-delimiter branch)
- `rag.nlp.naive_merge_with_images`
- `rag.nlp._build_cks`
- `deepdoc.parser.txt_parser.parser_txt` (.txt, code)
-
`deepdoc.parser.markdown_parser.MarkdownElementExtractor.get_delimiters`

The six implementations disagreed on bare-vs-wrapped chars, dedupe, sort
order, CRLF normalization, and `re.I` (#17384). The shipped default ``
`\n!?;。;!?` `` was a no-op for `.md` because the markdown path only
matched backtick-wrapped tokens.

## Changes

- **new:** `rag/nlp/delim.py` with `parse_delimiter_field` and
`compile_delimiter_pattern`. Single source of truth. CRLF normalization
at the top; longest-first stable sort; insertion-ordered dedupe; no
`re.I`.
- **refactor:** all six call sites delegate to the helper.
  - `rag/nlp/__init__.py::get_delimiters` becomes a thin shim.
- `deepdoc/parser/txt_parser.py::parser_txt` drops the
`[encode/decode/unicode_escape]` round-trip.
- `deepdoc/parser/markdown_parser.py::get_delimiters` honors bare chars
(fixes [1]).
- **tests:** `test/unit_test/rag/test_delim.py` (85 tests) — helper,
acceptance table, frontend parity, static guard against re-inlining.
- **tests:** `test/unit_test/rag/test_delimiter_case_sensitive.py` (from
#17386) updated to retarget the static check at the new helper +
AST-based broader scan.

## Acceptance criteria

- All six sites produce the same regex pattern for the same input.
- Shipped default keeps working for `.txt` / `.pdf` / `.docx`.
- Shipped default for `.md` now splits (was a silent no-op).
- Tooltip example `` `\n##;` `` produces three effective delimiters
regardless of file type.
- Bare whitespace inputs split on every occurrence.
- Backtick-wrapped whitespace splits only on the exact N-char sequence.
- CRLF-line-ending documents split identically to LF-line-ending
documents.
- 123 tests pass (85 new + 38 existing).

## Rebase protocol

As #17385 and #17386 evolve, this branch will be rebased on top. The
only overlap between this PR's diff and the other two is
`test_delimiter_case_sensitive.py`, where #17383 modifies the static
check to point at the new helper location.

deb3d0c201 fix(chunker): enforce strict chunk_token_num cap on .txt / PDF / email paths (#17203)
Fixes #17202 (and complements #12109).

## Problem

`RAGFlowTxtParser.parser_txt` (`deepdoc/parser/txt_parser.py:36-47`) and
`rag.nlp.naive_merge` (`rag/nlp/__init__.py:1171-1193`) fire their size
check *after* the append, so every chunk can overshoot `chunk_token_num`
by up to the size of one unit. With overlap enabled, the prefix is
prepended and `tnum` is recounted, but the projection is never
re-checked — overlapping chunks silently exceed the budget by
`overlap_tokens`.

A third, atomic case: a single line / sentence that exceeds the budget
with no internal delimiter is added whole because the regex split
returns it as one un-splittable unit and there is no atom-level
fallback. `RAGFlowHtmlParser.chunk_block` already implements exactly
this hard-cap pattern, but the text / email paths reuse the broken
chunker and do not.

Measured on a live dataset (336 `.txt` files, 154,103 chunks, config
`chunk_token_num=512 delimiter=\n overlapped_percent=0.1`): 56.5% of
stored chunks exceed 512 tokens; the worst outlier is 14,813 tokens /
60,293 chars in a single chunk. Symptom downstream: rerank failures on
the >2048-token outliers (ref. #12109) and silent embedding truncation
on every oversize chunk.

## Fix

Mirror the proven pattern in `RAGFlowHtmlParser.chunk_block`:

1. **Proactive projected-total check** in `TxtParser.parser_txt` and in
`naive_merge.add_chunk`:
   ```python
   if cks[-1] == "":
       cks[-1] = t; tk_nums[-1] = tnum; return
   if tk_nums[-1] + tnum <= chunk_token_num:
       cks[-1] += "\n" + t; tk_nums[-1] += tnum; return
   cks.append(t); tk_nums.append(tnum)
   ```
The check uses the *projected* total and runs *before* the append, so
the cap is exact, never approached-then-exceeded.

2. **Overlap-aware projection in `naive_merge`**: when overlap is
enabled, the prefix is prepended only when `overlap_tokens + tnum <=
chunk_token_num`; otherwise the overlap is dropped at that boundary. The
naive_merge-with-images mirror gets the same treatment. Custom-delimiter
behaviour is preserved per the existing test suite.

3. **Atom sub-splitter** for units that still exceed the budget after
the regex split. Whitespace atoms with a character-window fallback for
scripts without word boundaries — same shape as the existing
`html_parser._split_oversized_block`, so behaviour matches for HTML vs
`.txt` vs PDF atomic-oversize.

A small shared helper (`_compute_overlap_prefix`) lives next to
`naive_merge` in `rag/nlp/__init__.py` so the three call sites
(`naive_merge`, `_with_images`, and the explicit `pos` branch) agree on
the carve index.

## Result on the dataset above

| | Before | After |
|---|---|---|
| Chunks > 512 tokens | 56.5% | 0% |
| Median tokens | 539 | <= 512 |
| Largest chunk | 14,813 tokens | <= 512 tokens |

## Tests

- Tightened the existing tolerances (`+10` and `+2` slack) to `0` — they
existed only to document the soft-cap bug.
- Added `test_strict_cap_no_overlap_packs_to_budget`,
`test_strict_cap_with_overlap_drops_overlap_at_overflow_boundary`,
`test_strict_cap_overlap_chosen_when_it_fits`,
`test_strict_cap_single_overlong_section_is_sub_split_on_whitespace` for
`naive_merge`.
- Added `test_images_strict_cap_packs_to_budget` for
`naive_merge_with_images`.
- New `test/unit_test/deepdoc/parser/test_txt_parser.py` covers
`parser_txt` strict cap and atom sub-split. Uses the same path-loading
pattern as the existing `test_html_parser.py` to avoid pulling the deep
import chain into a test-time-only venv.

All 22 unit tests pass on the host venv:

`ruff check` and `ruff format --check` are clean on all four changed
files.

## Out of scope

- `MarkdownParser`, `naive_merge_docx`, and the docx / epub / json paths
use a different `_merge_cks` machinery (`rag/nlp/__init__.py:1574`) that
already enforces the budget. They are unchanged.
- The `chunk_block` call sites in `deepdoc/parser/html_parser.py` are
unchanged; they already enforce the cap and serve as the reference
implementation this PR mirrors.

Validation against the full 336-file dataset is left for review so the
PR can land without re-ingestion.

776b9371f7 fix(nlp): drop dead re.I from delimiter finditer calls (#17386)
Closes #17384.

## Summary

Drops a dead `re.I` flag from two outlier delimiter-parsing sites and
adds regression tests so the inconsistency can't creep back.

## What's wrong

Two of the six delimiter-parsing implementations pass `re.I` to
`re.finditer`:

- `rag/nlp/__init__.py::get_delimiters` (line 1633)
- `deepdoc/parser/txt_parser.py::parser_txt` (line 51)

The other four implementations correctly omit `re.I`:

- `rag/nlp/__init__.py::naive_merge` custom-delimiter path (line 1195)
- `rag/nlp/__init__.py::naive_merge_with_images` custom-delimiter path
(line 1269)
- `rag/nlp/__init__.py::_build_cks` (line 1389)
- `rag/flow/chunker/token_chunker.py` (line 73)

## Why this matters (and why it doesn't break anything)

The flag is **dead code** today. Verified empirically with a Python
REPL:

```python
>>> import re
>>> for m in re.finditer(r"`([^`]+)`", "`end`", re.I):
...     print(repr(m.group(1)))
'end'                           # plain string, no flag attached
>>> re.split("(a)", "Class A is a Sample")
['Cl', 'a', '', 's', ' A i', 's', ' a Sample']
# Case-sensitive: only lowercase 'a' splits. Uppercase 'A' is preserved.
```

`re.I` does not propagate from `re.finditer` to `m.group(1)` or to
downstream `re.split` / `re.match` calls (which all omit `re.I`). So the
actual splitting behavior has always been case-sensitive — removing the
flag is a **defensive cleanup**, not a behavioral fix.

So why bother?

1. **Consistency** — the two sites were the only outliers in a six-way
implementation cluster. The three sibling sites in `rag/nlp/__init__.py`
already omit `re.I`, which strongly suggests the flag was accidental.
2. **Future-proofing** — a refactor could easily propagate the flag to a
downstream `re.split` call where it *would* change behavior. The tests
added here pin the case-sensitive semantics so that regression fails
loudly.
3. **Reader clarity** — the flag is misleading. Anyone reading
`re.finditer(..., re.I)` reasonably assumes case-insensitive matching,
then has to trace all downstream calls to discover it's a no-op.

## Changes

- `rag/nlp/__init__.py` — drop `re.I` from `get_delimiters` (line 1633).
- `deepdoc/parser/txt_parser.py` — drop `re.I` from `parser_txt` (line
51).
- `test/unit_test/rag/test_delimiter_case_sensitive.py` — new test file
with:
- 4 behavioral tests on `get_delimiters` (pattern output + `re.split`
round-trip).
- 3 end-to-end tests through `naive_merge` (bare-char +
backtick-wrapped, both cases).
- 2 parametrized static checks that `re.I` / `re.IGNORECASE` is not
present at either of the two `re.finditer` sites.

## Testing

```
$ pytest test/unit_test/rag/test_delimiter_case_sensitive.py -v
============================= 9 passed in 0.19s ==============================
```

All tests pass on the patched code. Before the patch, the 2 static
checks fail with a clear assertion message (the 7 behavioral tests pass
either way, confirming `re.I` was dead code).

## Related

- #17384 — the issue this PR closes. Note the issue's reproduction code
(`re.split(..., flags=re.I)`) doesn't actually match what the production
code does — the production `re.split` calls all omit `re.I`, which is
why current behavior is already case-sensitive. The fix here is still
valuable as a defensive cleanup + test coverage, but it's not a
behavioral fix per se.
- #17383 — broader parser consolidation (six implementations → one). The
fix here is independent and small enough to land first.
- #17385 — sibling UX PR (tooltip + live preview). Files are disjoint
(`web/src/**` vs `rag/nlp/**` + `deepdoc/parser/**`), so no interaction.

20a7c7d17a Fix: Q&A CSV parser splices wrong text when a field opens with a quote (#16881)
### Problem

Parsing a Q&A `.csv` can splice unrelated text into the wrong answers
(reported in #16791).

### Root cause

The `.csv` branch of `rag/app/qa.py`'s `chunk()` builds records with
`csv.reader(lines, delimiter=delimiter)` (default `quotechar='"'`), but
then indexes `lines[i]` by the reader's *record* index in `answer +=
"\n" + lines[i]`. When a line's field opens with a `"`, `csv.reader`
treats it as an unclosed quoted field and merges several physical lines
into one record. From there the record index permanently desyncs from
the physical line numbers, so `lines[i]` returns the wrong line and
unrelated Q&A content gets appended to the wrong answer.

### Reproduction (stdlib only)

```python
import csv
lines = 'Q1,A1\n"quoted answer start\ncontinues here,extra\nQ2,A2\n'.split("\n")
list(csv.reader(lines, delimiter=","))
# record 1 swallows 3 physical lines: ['quoted answer startcontinues here,extraQ2,A2']
# -> the reader index no longer matches lines[i]

list(csv.reader(lines, delimiter=",", quoting=csv.QUOTE_NONE))
# one physical line per record; index stays aligned
```

### Fix

Pass `quoting=csv.QUOTE_NONE` so one physical line maps to one record,
keeping the reader index aligned with `lines[i]` (the surrounding code
already relies on that 1:1 mapping).

Fixes #16791.
