## What it is
A fast, dependency-free TypeScript fuzzy search library for searching entities by names and terms, powered by a suffix array and n-gram character sorting. It works in both browser and Node.js environments and supports multilingual text with dynamic index updates.

## Use cases
- add fuzzy search autocomplete to a web app
- search a list of names with typos in the browser
- implement multilingual client-side search over entities
- build a fast prefix and substring search index in JavaScript
- fuzzy match user input against a small dataset under 10ms
- search objects by id and name fields in a frontend app

## When to choose
- you need fast client-side fuzzy search with no dependencies
- your dataset is small to medium and must be indexed in the browser
- you need multilingual, language-agnostic string matching
- you want to insert, update, and remove indexed entities dynamically

## When to avoid
- you need full-text search over large corpora or server-scale datasets
- you need a hosted search service with analytics and relevance tuning
- you need semantic or vector-based search rather than string matching
