4800e25dd6 best: score 0.5541 (recall 0.5759, ndcg 0.4670) 
- DENSE_PREFETCH_K 80 → 120
- RERANK_LIMIT 25 → 35
- add question.text as extra dense when differs from search_text

c0f2d52f70 best: score 0.5496 (recall 0.5698, ndcg 0.4690) 
Search improvements on top of v1.0 index:
- RERANK_LIMIT 17 → 25
- prefilter with keyword-boosted stragglers (KEYWORD_BOOST_EXTRA=10)
- dense/sparse queries prefer search_text, keywords always in sparse
- variants+hyde as extra dense queries (up to 3)
- message_id score aggregation (rerank head full RRF, tail with k=60)

19fec2361e Fix 500 error: replace datetime_range with range in Qdrant filter 
qdrant-client 1.15.1 does not support datetime_range in FieldCondition.
Use models.Range with string comparison (same as Lotus reference).
Also wrap date filter in try-except to prevent crash on bad date format.

4ecba7d35a Migrate to multi-file architecture: smarter chunking + fixed RERANK_LIMIT 
index: message-based windowed chunking (5 msgs/1h gap), better unicode
cleaning, separate dense (with timestamps)/sparse content renderers,
BM25 preload on startup, ThreadPoolExecutor(4), UVICORN_WORKERS=4,
Dockerfile copies all *.py

search: proper multi-module structure (query_builder, retrieval, rerank,
aggregation), RERANK_LIMIT 60→15 (fixes 429 errors), extra dense vectors
for variants/hyde, date+asker metadata filters, httpx pool (100/20/30s),
BM25 preload on startup, Dockerfile copies all *.py

68/68 unit tests passing
