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 https://github.com/tobi/qmd

Setup

bash

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

bash

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 <num>
```
: number of results
```
-c, --collection <name>
```
: restrict to a collection
```
--all --min-score <num>
```
: return all matches above a threshold
```
--json
```
/
```
--files
```
: agent-friendly output formats
```
--full
```
: return full document content

Retrieve

bash

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

bash

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):

bash

# 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?".
