From f6400cd73652721731ead38742f56265180d2c5f Mon Sep 17 00:00:00 2001 From: Alex Date: Sat, 20 Jun 2026 21:54:23 +0100 Subject: [PATCH 1/9] feat: per-source RAG configuration (retrieval strategies, chunking, exposure, prescreen) Introduces a per-source config contract that makes RAG behavior strategy-dispatched instead of a single hardcoded path. Every source gains a validated JSONB config; an empty/absent config reproduces current behavior byte-for-byte, and the whole path is gated by PER_SOURCE_RETRIEVAL_ENABLED. Foundation: sources.config JSONB column + migration 0022_source_config; SourceConfig/ChunkingConfig/RetrievalConfig pydantic models (strict on write, lenient on read); ChunkerCreator and RetrieverCreator.register registries; config threaded through the upload routes, ingest/remote/connector workers, and reingest. Retrieval: a Dispatcher groups sources by retriever key (all-classic collapses to today's single ClassicRAG under one shared token budget; non-classic retrievers get their own instance), removing the previous single-global-retriever collapse in stream_processor. Per-source chunks, score_threshold (honored for pgvector/mongodb, safely ignored elsewhere), and rephrase_query toggle. New PATCH /api/sources//config with team-aware (effective_write_owner) authz and a requires_reingest signal. Chunking strategies: recursive, markdown, parent_child (selectable per source; re-ingest to apply). Search exposure: per-source prefetch vs agentic_tool for agentic/research agents. Map-reduce prescreen: optional LLM relevance pre-filter implemented as a composable post-retrieval stage that wraps any retriever. Backend and frontend (shared Retrieval options panel + edit modal) with tests; backend suite and frontend vitest green. Excludes the wiki and GraphRAG flagships. --- application/agents/tools/internal_search.py | 21 +- .../alembic/versions/0022_source_config.py | 41 ++ .../api/answer/services/stream_processor.py | 169 +++++- application/api/internal/routes.py | 16 + application/api/user/sources/routes.py | 93 +++ application/api/user/sources/upload.py | 41 ++ application/api/user/tasks.py | 7 +- application/core/settings.py | 12 +- application/parser/chunking.py | 23 +- application/parser/chunking_creator.py | 57 ++ application/parser/chunking_strategies.py | 224 +++++++ application/retriever/classic_rag.py | 63 +- application/retriever/dispatcher.py | 321 ++++++++++ application/retriever/retriever_creator.py | 5 + application/retriever/stages/__init__.py | 1 + application/retriever/stages/prescreen.py | 237 ++++++++ application/storage/db/models.py | 4 + .../storage/db/repositories/sources.py | 22 +- application/storage/db/source_config.py | 132 +++++ application/vectorstore/faiss.py | 3 + application/vectorstore/milvus.py | 3 + application/vectorstore/mongodb.py | 14 +- application/vectorstore/pgvector.py | 38 +- application/vectorstore/qdrant.py | 3 + application/worker.py | 66 ++- frontend/src/api/endpoints.ts | 1 + frontend/src/api/services/userService.ts | 6 + frontend/src/locale/en.json | 64 +- frontend/src/models/misc.ts | 46 ++ frontend/src/settings/SourceConfigModal.tsx | 240 ++++++++ frontend/src/settings/Sources.tsx | 34 +- .../components/RetrievalOptions.test.tsx | 166 ++++++ .../settings/components/RetrievalOptions.tsx | 547 ++++++++++++++++++ frontend/src/upload/Upload.tsx | 24 + tests/agents/test_internal_search_tool.py | 31 +- .../answer/test_stream_processor_exposure.py | 116 ++++ tests/api/user/sources/test_routes.py | 157 +++++ tests/api/user/test_tasks.py | 11 +- tests/parser/test_chunking.py | 16 +- tests/parser/test_chunking_creator.py | 75 +++ tests/parser/test_chunking_strategies.py | 149 +++++ tests/retriever/__init__.py | 0 tests/retriever/test_prescreen.py | 176 ++++++ tests/storage/db/repositories/test_sources.py | 24 + tests/storage/db/test_migration_0022.py | 73 +++ tests/storage/db/test_source_config.py | 138 +++++ tests/test_dispatcher.py | 321 ++++++++++ tests/test_retriever.py | 103 ++++ tests/vectorstore/test_faiss.py | 28 + tests/vectorstore/test_mongodb.py | 30 + tests/vectorstore/test_pgvector.py | 19 + tests/worker/test_ingest_worker.py | 87 +++ tests/worker/test_reingest_source_worker.py | 89 +++ 53 files changed, 4313 insertions(+), 74 deletions(-) create mode 100644 application/alembic/versions/0022_source_config.py create mode 100644 application/parser/chunking_creator.py create mode 100644 application/parser/chunking_strategies.py create mode 100644 application/retriever/dispatcher.py create mode 100644 application/retriever/stages/__init__.py create mode 100644 application/retriever/stages/prescreen.py create mode 100644 application/storage/db/source_config.py create mode 100644 frontend/src/settings/SourceConfigModal.tsx create mode 100644 frontend/src/settings/components/RetrievalOptions.test.tsx create mode 100644 frontend/src/settings/components/RetrievalOptions.tsx create mode 100644 tests/api/answer/test_stream_processor_exposure.py create mode 100644 tests/parser/test_chunking_creator.py create mode 100644 tests/parser/test_chunking_strategies.py create mode 100644 tests/retriever/__init__.py create mode 100644 tests/retriever/test_prescreen.py create mode 100644 tests/storage/db/test_migration_0022.py create mode 100644 tests/storage/db/test_source_config.py create mode 100644 tests/test_dispatcher.py diff --git a/application/agents/tools/internal_search.py b/application/agents/tools/internal_search.py index ec53b109..a622cce4 100644 --- a/application/agents/tools/internal_search.py +++ b/application/agents/tools/internal_search.py @@ -4,6 +4,7 @@ from typing import Dict, List, Optional from application.agents.tools.base import Tool from application.core.settings import settings +from application.retriever.dispatcher import build_dispatcher from application.retriever.retriever_creator import RetrieverCreator logger = logging.getLogger(__name__) @@ -31,8 +32,7 @@ class InternalSearchTool(Tool): def _get_retriever(self): if self._retriever is None: - self._retriever = RetrieverCreator.create_retriever( - self.config.get("retriever_name", "classic"), + retriever_kwargs = dict( source=self.config.get("source", {}), chat_history=[], prompt="", @@ -46,6 +46,20 @@ class InternalSearchTool(Tool): api_key=self.config.get("api_key", settings.API_KEY), decoded_token=self.config.get("decoded_token"), ) + + def _legacy_classic(): + return RetrieverCreator.create_retriever( + self.config.get("retriever_name", "classic"), + **retriever_kwargs, + ) + + # Dispatch per-source so on-demand agentic search honours the same + # per-source config as pre-fetch;
