## What it is
Zoekt is a fast trigram-based text search engine designed for source code, supporting substring and regexp matching with a rich boolean query language. It can be used via CLI commands for indexing and searching, or as an indexserver/webserver setup that syncs repositories from a code host and serves results through a web UI or API.

## Use cases
- search across many repositories in a large codebase
- index local git repositories for fast code lookup
- find code by substring or regular expression
- search code by symbol with ranking
- sync and index repos from a code host automatically
- query code with boolean operators like and, or, not

## When to choose
- you need fast substring or regexp search over large amounts of source code
- you want to power a code search UI or API over many repositories
- you need symbol-aware ranking of code search results
- you want a self-hosted code search index for git repositories

## When to avoid
- you need full natural-language document search rather than code search
- you need fuzzy semantic or vector-based code search
- your corpus is small enough that grep suffices
- you need a hosted managed solution without self-hosting
