Qmd

Fast local search for markdown files, notes, and docs using qmd CLI. Use instead of `find` for file discovery. Combines BM25 full-text search, vector semantic search, and LLM reranking—all running locally. Use when searching for files, finding code, locating documentation, or discovering content in indexed collections.

File contents

qmd — Fast Local Markdown Search

When to Use

Finding files — use instead of find across large directories (avoids hangs)
Searching notes/docs — semantic or keyword search in indexed collections
Code discovery — find implementations, configs, or patterns
Context gathering — pull relevant snippets before answering questions

Quick Reference

Search (most common)

# Keyword search (BM25)
qmd search "alpaca API" -c projects

# Semantic search (understands meaning)
qmd vsearch "how to implement stop loss"

# Combined search with reranking (best quality)
qmd query "trading rules for breakouts"

# File paths only (fast discovery)
qmd search "config" --files -c kell

# Full document content
qmd search "pattern detection" --full --line-numbers

Collections

# List collections
qmd collection list

# Add new collection
qmd collection add /path/to/folder --name myproject --mask "*.md,*.py"

# Re-index after changes
qmd update

Get Files

# Get full file
qmd get myproject/README.md

# Get specific lines
qmd get myproject/config.py:50 -l 30

# Get multiple files by glob
qmd multi-get "*.yaml" -l 50 --max-bytes 10240

Output Formats

--files — paths + scores (for file discovery)
--json — structured with snippets
--md — markdown formatted
-n 10 — limit results

Tips

Always use collections (-c name) to scope searches
Run qmd update after adding new files
Use qmd embed to enable vector search (one-time, takes a few minutes)
Prefer qmd search --files over find for large directories
