## Summary
- Stop pulling chunk vectors (`q_*_vec`) back from Elasticsearch in the
main retrieval path. ES already knows them; shipping them was pure
bandwidth/memory overhead.
- Recover the per-chunk cosine similarity via a second KNN-only ES call
filtered by the candidate chunk ids. The new `_score` is merged with
locally computed term similarity using the user-configured
`vector_similarity_weight`.
- Lazily fetch the chunk embedding only for the chunks
`insert_citations` actually needs.
## Details
**`rag/nlp/search.py`**
- `Dealer.search`: no longer appends `q_*_vec` to the ES select list.
OceanBase still gets it (its rerank path is unchanged).
- New `Dealer._knn_scores(sres, idx_names, kb_ids)`: a `MatchDenseExpr`
over the cached query vector filtered by `id IN sres.ids`, returning
`{chunk_id: cosine_score}` via ES `_score`.
- New `Dealer.rerank_with_knn(...)`: term similarity from
`qryr.token_similarity` plus the ES-supplied KNN score, combined with
`tkweight`/`vtweight` and the existing rank-feature bonus.
- New `Dealer.fetch_chunk_vectors(chunk_ids, tenant_ids, kb_ids, dim)`:
on-demand vector fetch for citation use.
- `Dealer.retrieval` routes Infinity → unchanged, OceanBase → existing
local `rerank`, ES → new KNN-score path.
**`common/doc_store/es_conn_base.py`**
- New `get_scores(res)` helper returning `{_id: _score}` directly from
hit headers (ES doesn't surface `_score` through `get_fields`).
**`api/db/services/dialog_service.py`**
- New top-level `_hydrate_chunk_vectors(...)` helper. On ES it
back-fills `ck["vector"]` from `fetch_chunk_vectors` right before
`insert_citations`. No-op on Infinity / OB (their chunks already carry
vectors).
- Both `decorate_answer` closures became `async` and are `await`-ed at
all call sites in `async_chat` and `async_ask`.
## Backend behavior
| Backend | Returns chunk vec in main search | Sim source | Vectors for
citations |
|---|---|---|---|
| ES | No | second KNN call (`_score`) merged with term sim | fetched on
demand |
| Infinity | No (unchanged) | normalized `_score` | already on chunks |
| OceanBase | Yes (kept) | local hybrid rerank | already on chunks |
## Test plan
### What problem does this PR solve?
Fixes#14570. On OpenSearch backends (`DOC_ENGINE=opensearch`) every
document-metadata write failed with `'OSConnection' object has no
attribute 'create_doc_meta_idx'`, so both `PATCH
/api/v1/datasets/{ds}/documents/{doc}` with `meta_fields` and `POST
/api/v1/datasets/{ds}/metadata/update` were unusable while every other
document operation (retrieval, parsing, name update, chunk management)
worked correctly on the same OpenSearch cluster.
The bug runs deeper than the missing method name in the error message
suggests. `DocMetadataService` also reached into
`settings.docStoreConn.es.*` directly for the index refresh, the
scripted partial update, and the count call, which means that even after
adding `create_doc_meta_idx` to `OSConnection` the very next call in the
same metadata flow would still raise `AttributeError` because
`OSConnection` exposes `self.os` rather than `self.es`. Fixing only the
reported symptom would have moved the failure one line down without
restoring the feature.
This PR adds a uniform document-metadata dispatch surface to both
connection classes so they present the same abstract API, and routes the
service layer through that surface via `getattr` guards instead of
poking at backend-specific attributes. The four new methods on
`OSConnection` and `ESConnectionBase` are `create_doc_meta_idx`,
`refresh_idx`, `count_idx`, and `replace_meta_fields`.
`OSConnection.create_doc_meta_idx` reuses the existing
`conf/doc_meta_es_mapping.json` schema in the OpenSearch `body=` form
because OpenSearch and Elasticsearch share the same index-creation
payload, and `replace_meta_fields` emits a full scripted assignment
(`ctx._source.meta_fields = params.meta_fields`) on both backends so
removed keys actually disappear instead of being preserved by deep-merge
semantics.
The `getattr`-guarded dispatch in `DocMetadataService` keeps the
existing fall-through paths intact for Infinity and OceanBase, which
continue to rely on their search-based count fallback and on the
delete-then-insert metadata replacement they used before, so this change
is strictly additive for those two backends.
Verification: `pytest
test/unit_test/rag/utils/test_opensearch_doc_meta.py` runs 16 new unit
tests that pass locally and pin the `OSConnection` dispatch surface, the
`create_doc_meta_idx` short-circuit when the index already exists, the
mapping-file payload routing, the `IndicesClient.create` failure path,
the `refresh_idx` and `count_idx` success and error sentinels, and the
full-assignment script emitted by `replace_meta_fields`. The test module
stubs `common.settings` and `rag.nlp` at import time so the suite runs
without the heavy backend SDKs that the rest of the repository pulls in
transitively.

Concurrent CREATE TABLE / CREATE INDEX / DROP TABLE on the same Infinity
instance can race on the catalog counter (e.g. db|1|next_table_id) and
fail with error 9003 "Resource busy" instead of waiting on a lock. Two
users creating a knowledge base at the same instant, or any deployment
with multiple backend workers behind one Infinity, can hit it.
Wrap the metadata paths in create_idx, create_doc_meta_idx, and
delete_idx with exponential backoff + jitter (5 attempts, 50ms base).
The wrapped operations already use ConflictType.Ignore, so retrying is
idempotent — worst case the second attempt is a no-op against an
already-created table. Tunable via INFINITY_META_RETRY_MAX /
INFINITY_META_RETRY_BASE_DELAY_MS.
Repro: stress 30 concurrent POST /api/v1/datasets against a 4-worker
backend → ~50% of requests fail without the patch (Resource busy from
the second worker that hits the counter), 100% succeed with it. At 100
concurrent requests, all 100 succeed in ~1.2s; the retry budget never
exhausted in our tests.
Scope is limited to metadata paths only — data-path operations (INSERT
chunks, SELECT for retrieval) go through per-table code paths and don't
share the contended counter.

## Summary
Fixes#5939
Entity names containing single quotes (e.g., `投影直线L'`) caused SQL syntax
errors when building filter conditions for Infinity queries, due to
unescaped string interpolation in `equivalent_condition_to_str`.
## Changes
In `common/doc_store/infinity_conn_base.py`, added `.replace("'", "''")`
escaping for string values in two branches of
`equivalent_condition_to_str` where it was missing:
1. **`field_keyword` branch with non-list value** (line 190): The list
branch already escaped single quotes on line 183, but the single-string
branch did not.
2. **Plain string value branch** (line 209): Direct f-string
interpolation `{k}='{v}'` was vulnerable to unescaped quotes.
Both fixes use the same SQL-standard escape pattern (`'` → `''`) already
applied elsewhere in this method.
## How to Test
1. Upload a document containing entity names with single quotes.
2. Enable Knowledge Graph (GraphRAG) in the parsing configuration.
3. Initiate document parsing — it should complete without SQL syntax
errors.
## Note
The original issue also reported a typo (`dge_graph_kwd` instead of
`knowledge_graph_kwd`), which has already been fixed in the current
codebase.

### What problem does this PR solve?
Resolve#14137 .
### Problem
Graph resolution succeeds (nodes/edges merged, pagerank updated), but
the subsequent burst of Infinity write operations in `set_graph`
exhausts the connection pool with `TOO_MANY_CONNECTIONS` errors. Root
causes:
1. **Hardcoded pool size** — `infinity_conn_pool.py` hardcoded
`ConnectionPool(max_size=4)` on initial creation and `max_size=32` on
refresh. Operators cannot tune this without patching code.
2. **No retry on transient failures** — a single `TOO_MANY_CONNECTIONS`
on edge deletes or chunk inserts kills the entire resolution+community
pipeline with no retry.
### Changes
#### `common/doc_store/infinity_conn_pool.py`
- Read `ConnectionPool` `max_size` from the `INFINITY_POOL_MAX_SIZE`
environment variable (default: `4`), applied consistently to both
initial creation and refresh paths.
- Log the actual pool size on startup for easier debugging.
#### `rag/graphrag/utils.py` — `set_graph()`
- **Edge deletes**: add exponential-backoff retry (3 attempts, 1s/2s/4s
delays) so transient `TOO_MANY_CONNECTIONS` errors are retried instead
of failing the entire job. Concurrency continues to be gated by the
existing `chat_limiter`.
- **Batch inserts**: add exponential-backoff retry (3 attempts, 1s/2s/4s
delays) for the same reason.

## Summary
Fixes#13996
Replace `json.load(open(...))` with `with open(...) as f: json.load(f)`
in two files to ensure file descriptors are properly closed.
**Affected files:**
- `common/doc_store/infinity_conn_base.py` — schema loading for Infinity
doc store
- `api/db/init_data.py` — agent template loading at startup
## Why this matters
In a long-running server process like RAGFlow, leaked file descriptors
from `json.load(open(...))` can accumulate over time. While CPython's
refcounting usually cleans these up, it's not guaranteed (especially
under memory pressure or with alternative Python runtimes), and can lead
to `OSError: [Errno 24] Too many open files`.
## Test plan
- [ ] Verify Infinity doc store schema loading still works correctly
- [ ] Verify agent templates load correctly on startup

**What problem does this PR solve?**
When loading JSON mapping/schema files, the code used
json.load(open(path)) without closing the file. The file handle stayed
open until garbage collection, which can leak file descriptors under
load (e.g. repeated reconnects or migrations).
**Type of change**
[x] Bug Fix (non-breaking change which fixes an issue)
**Change**
Replaced json.load(open(...)) with a context manager so the file is
closed after loading:
with open(fp_mapping, "r") as f: ... = json.load(f)
**Files updated**
rag/utils/opensearch_conn.py – mapping load (1 place)
common/doc_store/es_conn_base.py – mapping load + doc_meta_mapping load
(2 places)
common/doc_store/infinity_conn_base.py – schema loads in _migrate_db,
doc metadata table creation, and SQL field mapping (4 places)
Behavior is unchanged; only resource handling is fixed.
