qmd - Quick Markdown Search

Fast local search engine for markdown notes, documentation, and Claude session history.

Quick Start

# Keyword search (instant, preferred)
qmd search "authentication flow"

# Get full document
qmd get "path/to/file.md"

# Search specific collection
qmd search "react hooks" -c claude-sessions

Search Modes

qmd search (Default - Use This)

BM25 keyword matching. Instant results.

qmd search "error handling"
qmd search "typescript generics" -n 10
qmd search "api design" --json

qmd vsearch (Use Sparingly)

Vector similarity search. Slower - loads local models on each run.

qmd vsearch "concepts similar to dependency injection"

qmd query (Avoid)

Hybrid search with LLM reranking. Slowest, often less reliable.

Guidelines

• Prefer qmd search - instant BM25 keyword matching
• Use qmd vsearch sparingly - slow due to model loading
• Avoid qmd query - hybrid search often unreliable
• Use --json or --files for agent-friendly output
• Use -c collection to narrow scope when you know the target
