Index once, search fast. ## When to use (trigger phrases) - "search my notes / docs / knowledge base" - "find related notes" - "retrieve a markdown document from my collection" - "search local markdown files" ## Default behavior (important) - Prefer `qmd search` (BM25). It's typically instant and should be the default. - Use `qmd vsearch` only when keyword search fails and you need semantic similarity (can be very slow on a cold start). - Avoid `qmd query` unless the user explicitly wants the highest quality hybrid results and can tolerate long runtimes/timeouts. ## Prerequisites - Bun >= 1.0.0 - macOS: `brew install sqlite` (SQLite extensions) - Ensure PATH includes: `$HOME/.bun/bin` Install Bun (macOS): `brew install oven-sh/bun/bun` ## Install `bun install -g https://github.com/tobi/qmd` ## Setup ``` qmd collection add /path/to/notes --name notes --mask "**/*.md" qmd context add qmd://notes "Description of this collection" # optional qmd embed # one-time to enable vector + hybrid search ``` ## What it indexes - Intended for Markdown collections (commonly `**/*.md`). - In our testing, "messy" Markdown is fine: chunking is content-based (roughly a few hundred tokens per chunk), not strict heading/structure based. - Not a replacement for code search; use code search tools for repositories/source trees. ## Search modes - `qmd search` (default): fast keyword match (BM25) - `qmd vsearch` (last resort): semantic similarity (vector). Often slow due to local LLM work before the vector lookup. - `qmd query` (generally skip): hybrid search + LLM reranking. Often slower than `vsearch` and may timeout. ## Performance notes - `qmd search` is typically instant. - `qmd vsearch` can be ~1 minute on some machines because query expansion may load a local model (e.g., Qwen3-1.7B) into memory per run; the vector lookup itself is usually fast. - `qmd query` adds LLM reranking on top of `vsearch`, so it can be even slower and less reliable for interactive use. - If you need repeated semantic searches, consider keeping the process/model warm (e.g., a long-lived qmd/MCP server mode if available in your setup) rather than invoking a cold-start LLM each time. ## Common commands ``` qmd search "query" # default qmd vsearch "query" qmd query "query" qmd search "query" -c notes # Search specific collection qmd search "query" -n 10 # More results qmd search "query" --json # JSON output qmd search "query" --all --files --min-score 0.3 ``` ## Useful options - `-n `: number of results - `-c, --collection `: restrict to a collection - `--all --min-score `: return all matches above a threshold - `--json` / `--files`: agent-friendly output formats - `--full`: return full document content ## Retrieve ``` qmd get "path/to/file.md" # Full document qmd get "#docid" # By ID from search results qmd multi-get "journals/2025-05*.md" qmd multi-get "doc1.md, doc2.md, #abc123" --json ``` ## Maintenance ``` qmd status # Index health qmd update # Re-index changed files qmd embed # Update embeddings ``` ## Keeping the index fresh Automate indexing so results stay current as you add/edit notes. - For keyword search (`qmd search`), `qmd update` is usually enough (fast). - If you rely on semantic/hybrid search (`vsearch`/`query`), you may also want `qmd embed`, but it can be slow. Example schedules (cron): ``` # Hourly incremental updates (keeps BM25 fresh): 0 * * * * export PATH="$HOME/.bun/bin:$PATH" && qmd update # Optional: nightly embedding refresh (can be slow): 0 5 * * * export PATH="$HOME/.bun/bin:$PATH" && qmd embed ``` If your Clawdbot/agent environment supports a built-in scheduler, you can run the same commands there instead of system cron. ## Models and cache - Uses local GGUF models; first run auto-downloads them. - Default cache: `~/.cache/qmd/models/` (override with `XDG_CACHE_HOME`). ## Relationship to Clawdbot memory search - `qmd` searches *your local files* (notes/docs) that you explicitly index into collections. - Clawdbot's `memory_search` searches *agent memory* (saved facts/context from prior interactions). - Use both: `memory_search` for "what did we decide/learn before?", `qmd` for "what's in my notes/docs on disk?".
