- Replace multiple consecutive spaces with single underscore for tag matching
(e.g., 'looking to the side' → 'looking_to_the_side')
- Support prefix/suffix matching for flexible multi-word autocomplete
(e.g., 'looking to the' → 'looking_to_the_side')
- Add comprehensive test coverage for multi-word scenarios
Test coverage:
- Multi-word exact match (Danbooru convention)
- Partial match with last token replacement
- Command mode with multi-word phrases
- Multiple consecutive spaces handling
- Backend LOG10 popularity weight validation
Fixes: 'looking to the side' input now correctly replaces with
'looking_to_the_side, ' (or 'looking to the side, ' with space replacement)
- Add LOG10(post_count) weighting to BM25 score for better relevance ranking
- Prioritize tag_name prefix matches above alias matches using CASE statement
- Remove frontend re-scoring logic to trust backend排序 results
- Fix pagination consistency: page N+1 scores <= page N minimum score
Key improvements:
- '1girl' (6M posts) now ranks #1 instead of #149 for search '1'
- tag_name prefix matches always appear before alias matches
- Popular tags rank higher than obscure ones with same prefix
- Consistent ordering across pagination boundaries
Test coverage:
- Add test_search_tag_name_prefix_match_priority
- Add test_search_ranks_popular_tags_higher
- Add test_search_pagination_ordering_consistency
- Add test_search_rank_score_includes_popularity_weight
- Update test data with 15 tags starting with '1'
Fixes issues with autocomplete dropdown showing inconsistent results
when scrolling through paginated search results.
Temporarily remove width constraints when measuring content to prevent
scrollWidth from being limited by narrow container. This fixes the issue
where dropdown width was incorrectly calculated as ~120px.
Also update test to match maxItems default value (100).
- Add token parsing to support include/exclude search terms using "-" prefix
- Implement token-based matching logic for relative path searches
- Improve search result sorting by prioritizing prefix matches and match position
- Add frontend test for multi-token highlighting with exclusion support
