v0.2.0

What's New

Search

• SearchFuzzy — typo-tolerant search via trigram OR-union tally, no bigram index needed
• SearchMulti — collect candidates once, score per strategy (map[string]ScoreFunc)
• WithLoose() — OR across terms (AND within each term)
• SearchRegex with trigram-accelerated boolean evaluation

tmp:// Overlay

• In-memory documents searchable alongside the LMDB index
• AddTmpFile, UpdateTmpFile, AppendTmpFile (shell >> semantics), RemoveTmpFile

ChunkCache

• NewChunkCache() — per-query cache for file content and chunked data
• Retrieve() for cached chunk content
• Copy() and InvalidateCaches() for read/write path separation

Chunkers

• BracketChunker — table-driven, line-oriented depth tracking
• IndentChunker — indentation-scoped, reuses BracketLang config
• MarkdownChunkFunc — honors fenced code blocks
• ChunkCallback API for streaming chunk processing
• CopyPairs exported; Attrs surfaced in ChunkResult

Performance

• NewSearchCache with pathToID reverse cache — >2x search speedup
• Coalesced T/W batch writes on add

Architecture

• Single LMDB subdatabase with prefix-distinguished records
• Chunk deduplication via SHA-256 content hash
• TxnHolder interface — records carry transaction context
• searchConfig receiver refactor for cleaner search internals
• RecordCounts, FileIDPaths, UnmarshalFHeader utilities

Removed

• Bigram index (too slow, too fat — SearchFuzzy handles the use case)
