flexsearch

What is flexsearch?

FlexSearch is a high-performance, full-text search library for JavaScript. It is designed to be fast and efficient, providing a variety of indexing and search capabilities. FlexSearch can be used in both Node.js and browser environments, making it versatile for different types of applications.

What are flexsearch's main functionalities?

Indexing

FlexSearch allows you to create an index and add documents to it. Each document is associated with a unique ID.

const FlexSearch = require('flexsearch');
const index = new FlexSearch();
index.add(1, 'Hello World');
index.add(2, 'Hi there');

Searching

You can perform searches on the indexed documents. The search results will return the IDs of the matching documents.

index.search('Hello', function(results) {
  console.log(results); // [1]
});

Asynchronous Search

FlexSearch supports asynchronous search operations, which can be useful for handling large datasets or integrating with other asynchronous workflows.

index.search('Hello').then(function(results) {
  console.log(results); // [1]
});

Custom Configuration

FlexSearch allows for extensive customization of the indexing and search process. You can configure encoding, tokenization, threshold, and resolution to suit your specific needs.

const customIndex = new FlexSearch({
  encode: 'icase',
  tokenize: 'forward',
  threshold: 0,
  resolution: 3
});
customIndex.add(1, 'Custom configuration example');
