## What it is
A tiny, blazing-fast JavaScript fuzzy search library that checks whether a needle string matches a haystack via in-order character matching. It is designed for fast filtering of options in autocomplete menus and lightweight user-input matching.

## Use cases
- filter autocomplete options based on partial user input
- fuzzy match a query string against a list of strings
- quickly check if characters of one string appear in order in another
- filter large lists in the browser with lightweight input
- implement typeahead search without heavy dependencies

## When to choose
- you need a tiny, dependency-free fuzzy matcher with excellent performance
- you only need boolean subsequence matching, not ranked or approximate results
- you are building an autocomplete or filter UI in JavaScript

## When to avoid
- you need Levenshtein distance or typo-tolerant approximate matching
- you need ranked, scored, or highlighted fuzzy search results
- you need full-text search over documents or an index

## Facets
- artifact type: library
- maturity: maintenance
- function: search-engine, parser
