## What it is
MiniSearch is a tiny, dependency-free in-memory full-text search engine written in TypeScript for browser and Node.js. It provides prefix and fuzzy matching, field boosting, ranking, and auto-suggestion for datasets that fit in process memory.

## Use cases
- add search-as-you-type to a web or mobile app
- implement client-side full-text search without a search server
- build autocomplete and query auto-suggestions
- search a small dataset with typo tolerance and fuzzy matching
- run offline search in the browser or an edge worker
- index documents in memory in a Node.js process

## When to choose
- your dataset fits in memory and you want zero-dependency, lightweight search
- you need fast client-side search without network latency or a backend
- you want prefix, fuzzy, and field-boosted search with a simple API

## When to avoid
- you need to index very large datasets that exceed process memory
- you need a distributed, persistent, or server-backed search engine like Elasticsearch
- you need advanced features like faceting, geosearch, or multi-node scaling

## Facets
- artifact type: library
- maturity: stable
- function: search-engine, http-client
- domain: web-development, frontend, developer-tools
- platform: browser, cross-platform
- tags: fulltext-search, fuzzy-search, autocomplete, autosuggestion, in-memory-index, typo-tolerance, zero-dependencies, typescript, search, nodejs, javascript
