Zimi v1.2.0 — Progressive Search, SQLite Title Index, Collections

Search

• Two-phase progressive search — Phase 1 returns instant title matches, Phase 2 fills in full-text results with live timer
• SQLite title indexes — persistent per-ZIM indexes built on first startup. Single-word queries under 1ms, multi-word via FTS5 under 2s
• FTS5 threshold — ZIMs with >2M entries skip FTS5 at build time. Enable on-demand from the manage UI

Collections

• Named collections — group ZIMs into sets for scoped search via API, MCP, or web UI
• Category-grouped picker — ZIMs organized by category when editing collections

Library Manager

• Server stats — request counts, latency, cache hit rates, title index status, disk usage
• On-demand deep search — build FTS5 for large ZIMs from the stats tab
• Safe delete — two-click confirmation prevents accidental collection deletion

Data

• ZIMI_DATA_DIR — dedicated data directory for indexes, cache, and config. Auto-migrates from v1.1
• Storage — title indexes use ~2–3% of total ZIM size on disk

Performance (55 ZIMs, spinning disk)

Scenario	Before	After
Title search (single word, cold)	40s	under 1ms
Title search (multi-word, cold)	40s+	under 2s
Full-text search	12–55s	unchanged
