qmd - Quick Markdown Search

Local search engine for Markdown notes, docs, and knowledge bases. 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 ## Setup __CODE_BLOCK_0__ ## 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 __CODE_BLOCK_1__ ## 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 __CODE_BLOCK_2__ ## Maintenance __CODE_BLOCK_3__ ### Keeping the index fresh Set up a cron job or hook to automatically re-index. For example, a daily 5 AM reindex: __CODE_BLOCK_4__ This ensures your vault search stays current as you add or edit notes. ## 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?".
