## What it is
A persistent, network-resilient full-text search library for JavaScript that runs in both the browser and Node.js. It lets developers build and query an inverted search index locally without needing a server-side search engine.

## Use cases
- add full-text search to a static site or web app
- build offline-first search that works without a network
- index and query JSON documents in Node.js
- embed a search engine in the browser without a backend
- create a persistent local search index for an app
- search documents client-side with no server dependency

## When to choose
- you need client-side or offline search without running a search server
- you want a lightweight embedded full-text index in JavaScript
- your dataset is small-to-medium and persistence in the browser or Node is important

## When to avoid
- you need distributed, multi-node search at large scale (use Elasticsearch or similar)
- you need advanced relevance tuning, faceting, or clustering out of the box
- your stack is not JavaScript

## Facets
- artifact type: library
- maturity: stable
- function: search-engine, nlp, serialization
- domain: web-development, frontend
- platform: browser, cross-platform
- tags: full-text-search, offline-first, persistent-index, javascript, search, natural-language-processing, nodejs
