Search Engine Upgrade: pg_trgm + RRF Fusion
Keyword search upgraded from ILIKE pattern matching to pg_trgm trigram matching with native Chinese support and real relevance scoring (0-1).
Results now use Reciprocal Rank Fusion (RRF) to merge vector semantic search and keyword exact search — entries found by both paths rank highest.
What you'll notice: searching for names, product codes, and technical terms is more accurate; Chinese queries no longer miss matching entries.
Knowledge Revision History (Compiled Truth + Timeline)
Every time you update knowledge via update_knowledge, KnowMine automatically saves the previous version.
New MCP tool get_knowledge_history lets you:
- See how a piece of knowledge evolved from first draft to current version
- Trace who made each change (user / AI Agent)
- Current content = Compiled Truth (always latest), history = Timeline (append-only)
Explicit Knowledge Links (Typed Links)
Beyond auto-discovered vector similarity, you can now tag semantic relationships between knowledge entries:
| Type | Meaning | Example |
|---|---|---|
based_on | Based on | "New analysis" based on "old research" |
refutes | Refutes | "New data" overturns "old conclusion" |
extends | Extends | "Follow-up" extends "original report" |
evolved_from | Evolved from | "v2 plan" evolved from "v1 plan" |
related_to | Related | General association |
