Search Commands

search (BM25 keyword search - fast)

qmd search "authentication flow" --json
qmd search "error handling" --json -n 10
qmd search "config" --json -c notes

vsearch (vector semantic search)

qmd vsearch "how does login work" --json
qmd vsearch "authentication best practices" --json -n 20

query (hybrid with LLM re-ranking - best quality)

qmd query "implementing user auth" --json
qmd query "deployment process" --json --min-score 0.5

Search Options

Option	Description
`-n NUM`	Number of results (default: 5, or 20 with --json)
`-c, --collection NAME`	Restrict to specific collection
`--min-score NUM`	Minimum score threshold
`--full`	Return complete document content in results
`--all`	Return all matches

Retrieval Commands

get (single document)

qmd get docs/guide.md --json
qmd get "#a1b2c3" --json
qmd get notes/meeting.md:50 -l 100 --json

multi-get (multiple documents)

qmd multi-get "docs/*.md" --json
qmd multi-get "api.md, guide.md, #abc123" --json
qmd multi-get "notes/**/*.md" --json --max-bytes 20480

Maintenance Commands

qmd update              # Re-index changed files
qmd status              # Check index health
qmd collection list     # List all collections

Search Mode Selection

Mode	Speed	Quality	Best For
search	Fast	Good	Exact keywords, known terms
vsearch	Medium	Better	Conceptual queries, synonyms
query	Slow	Best	Complex questions, uncertain terms

Performance note: vsearch and query have ~1 minute cold start latency for vector initialization. Prefer search for interactive use.
