Markdown Documentation Full-Text Search

Fast, indexed full-text search across Markdown documentation archives using SQLite FTS5 with BM25 relevance ranking.

When to Use

• Searching documentation archives for specific features, capabilities, or information
• Finding official source URLs to cite in reports
• Looking up technical specifications or configuration details
• Research across multiple documentation sources

Document Format Expected

Articles separated by --- delimiter with *Source: URL:

# Article Title

*Source: https://docs.example.com/path/to/article.html*

Article content here...

---

# Next Article Title

*Source: https://docs.example.com/another/article.html*

More content...

Quick Start

# 1. Index the documentation (one-time or when docs change)
scripts/docs.py index ./docs

# 2. Search
scripts/docs.py search "kubernetes backup" --max 5

# 3. Check index status
scripts/docs.py status

Primary Tool: docs.py

The unified CLI handles all operations:

Indexing

# Index documentation directory
scripts/docs.py index ./docs

# Force full rebuild
scripts/docs.py index ./docs --rebuild

# Custom database location
scripts/docs.py index ./docs --db /path/to/custom.db

Searching

# Basic search
scripts/docs.py search "kubernetes backup"

# Boolean operators
scripts/docs.py search "AWS AND S3 AND snapshot"

# Phrase search
scripts/docs.py search '"exact phrase match"'

# Prefix search
scripts/docs.py search "kube*"

# Exclude terms
scripts/docs.py search "backup NOT restore"

# Title-only search
scripts/docs.py search "kubernetes" --title-only

# Output formats
scripts/docs.py search "kubernetes" --format json
scripts/docs.py search "kubernetes" --format markdown

# More context around matches
scripts/docs.py search "kubernetes" --context 400

# Include full content in JSON
scripts/docs.py search "kubernetes" --format json --full-content

FTS5 Query Syntax

Getting Specific Articles

# Get article by partial URL or title
scripts/docs.py get "system_requirements" --full

# Find all matching articles
scripts/docs.py get "backup" --all

Status

# Check index statistics
scripts/docs.py status

Workflow for Research Tasks

Discovery Phase

# Check what's indexed
scripts/docs.py status

# Explore topics with broad searches
scripts/docs.py search "<feature>" --max 20

Research Phase

# Narrow down with boolean operators
scripts/docs.py search "<feature> AND <platform>"

# Find specific information
scripts/docs.py search "limitation OR restriction OR 'not supported'"

Citation Phase

Every search result includes the Source: URL — use this in your reports:

According to documentation, [finding]...

Source: https://docs.example.com/path/to/article.html

Multi-Source Setup

Each agent or project can have their own documentation and index:

~/docs/VendorA/
    ├── docs_part_01.md
    ├── docs.db      # Index lives with docs
    └── ...

~/docs/VendorB/
    ├── docs.md
    ├── docs.db
    └── ...

The docs.py script auto-detects the database location.

Advanced Scripts

For specialized needs:

• scripts/fts_search.py — Direct FTS5 search with more options
• scripts/index_docs.py — Standalone indexing
• scripts/list_sources.py — List all source URLs
• scripts/get_article.py — Direct article retrieval
• scripts/search_docs.py — Regex-based search (no index needed)

Research Patterns

For common search patterns (feature research, architecture, security, etc.), see references/search-patterns.md.

Example Session

# What's available?
scripts/docs.py status
# Output: Files indexed: 37, Articles indexed: 32065

# Find information
scripts/docs.py search "kubernetes backup" --max 5

# Narrow to specific platform
scripts/docs.py search "kubernetes AND AWS" --max 5

# Find limitations
scripts/docs.py search "limitation OR 'not supported'"

# Get full article for citation
scripts/docs.py get "system_requirements" --full

Best Practices

1. Index once, search many times — FTS5 is fast because it's indexed
2. Use boolean operators — AND, OR, NOT for precision
3. Phrase search for exact terms — "exact match" with quotes
4. Always cite sources — Include Source: URLs in reports
5. Rebuild periodically — Re-index when documentation updates
6. Use JSON for analysis — Pipe to jq or other tools for processing
