libsearch
A lightweight, index-free full-text search library for JavaScript with TF-IDF ranking.
What is libsearch?
libsearch is a lightweight JavaScript library that provides full-text search capabilities without requiring a pre-built index. It transforms search queries into regular expressions and uses a TF-IDF-like ranking algorithm to return relevant results from arrays of strings or objects. It solves the problem of adding simple, fast search to web applications without the complexity of setting up and maintaining a search index.
JavaScript developers building client-side web applications or Node.js projects that need to implement search functionality over small to medium datasets (up to thousands of documents). It's particularly useful for prototypes, personal projects, or applications where data changes frequently and indexing overhead is undesirable.
Developers choose libsearch for its simplicity and zero-configuration approach—it works out of the box without an indexing step. Its performance is sufficient for many real-time search scenarios, and it provides better ranking than basic string matching while remaining lightweight and easy to integrate.
