From 09a9b629eedebabd010f865de14a488e55776441 Mon Sep 17 00:00:00 2001 From: Brian Sparker Date: Wed, 19 Aug 2026 21:12:18 -0700 Subject: [PATCH] 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. --------- Co-authored-by: Brian Sparker Co-authored-by: Claude Opus 5 (1M context) --- docs/references/http_api_reference.md | 3 +- internal/service/web_search_provider.go | 165 +++++++++++- internal/service/web_search_provider_test.go | 251 ++++++++++++++++++ rag/utils/web_search_conn.py | 18 +- rag/utils/youcom_conn.py | 152 +++++++++++ .../test_session_sdk_routes_unit.py | 17 ++ .../rag/utils/test_web_search_conn.py | 44 +++ test/unit_test/rag/utils/test_youcom_conn.py | 210 +++++++++++++++ web/src/assets/svg/youcom.svg | 10 + web/src/components/web-search-form-field.tsx | 14 + web/src/constants/chat.ts | 9 + web/src/interfaces/database/chat.ts | 1 + web/src/locales/en.ts | 3 + web/src/locales/zh.ts | 3 + .../app-settings/use-chat-setting-schema.tsx | 2 + .../next-chats/chat/use-show-internet.test.ts | 55 +++- .../next-chats/chat/use-show-internet.ts | 5 +- .../next-chats/chat/web-search-api-key.ts | 28 +- 18 files changed, 981 insertions(+), 9 deletions(-) create mode 100644 rag/utils/youcom_conn.py create mode 100644 test/unit_test/rag/utils/test_youcom_conn.py create mode 100644 web/src/assets/svg/youcom.svg diff --git a/docs/references/http_api_reference.md b/docs/references/http_api_reference.md index 5088f30ef2..25b1592dfc 100644 --- a/docs/references/http_api_reference.md +++ b/docs/references/http_api_reference.md @@ -3032,10 +3032,11 @@ curl --request POST \ - `"use_kg"`: `boolean` - `"reasoning"`: `boolean` - `"cross_languages"`: `list[string]` - - `"web_search_provider"`: `string` The web search service to use.
