From ac936005e64ea4029026ad66ac550f9995b0fed2 Mon Sep 17 00:00:00 2001 From: Vedant Madane <6527493+VedantMadane@users.noreply.github.com> Date: Thu, 15 Jan 2026 12:15:55 +0530 Subject: [PATCH] fix: ensure deleted chunks are not returned in retrieval (#12520) (#12546) ## Summary Fixes #12520 - Deleted chunks should not appear in retrieval/reference results. ## Changes ### Core Fix - **api/apps/chunk_app.py**: Include \doc_id\ in delete condition to properly scope the delete operation ### Improved Error Handling - **api/db/services/document_service.py**: Better separation of concerns with individual try-catch blocks and proper logging for each cleanup operation ### Doc Store Updates - **rag/utils/es_conn.py**: Updated delete query construction to support compound conditions - **rag/utils/opensearch_conn.py**: Same updates for OpenSearch compatibility ### Tests - **test/testcases/.../test_retrieval_chunks.py**: Added \TestDeletedChunksNotRetrievable\ class with regression tests - **test/unit/test_delete_query_construction.py**: Unit tests for delete query construction ## Testing - Added regression tests that verify deleted chunks are not returned by retrieval API - Tests cover single chunk deletion and batch deletion scenarios --- api/apps/chunk_app.py | 4 +- api/db/services/document_service.py | 28 +- rag/utils/es_conn.py | 53 ++-- rag/utils/opensearch_conn.py | 55 ++-- .../test_retrieval_chunks.py | 89 +++++- test/unit/test_delete_query_construction.py | 291 ++++++++++++++++++ 6 files changed, 472 insertions(+), 48 deletions(-) create mode 100644 test/unit/test_delete_query_construction.py diff --git a/api/apps/chunk_app.py b/api/apps/chunk_app.py index 20891033a..e900d0bff 100644 --- a/api/apps/chunk_app.py +++ b/api/apps/chunk_app.py @@ -223,7 +223,9 @@ async def rm(): e, doc = DocumentService.get_by_id(req["doc_id"]) if not e: return get_data_error_result(message="Document not found!") -
