Introduction to FlexSearch

FlexSearch is a high-performance, full-text search library for JavaScript. It provides both natural language searching and flexible indexing capabilities. With FlexSearch, developers can achieve the best possible search performance while maintaining flexibility and ease of use.

Getting Started

  const flexsearch = require("flexsearch");

  // Create an index
  const index = new flexsearch.Index();

Indexing Documents

  // Add documents to the index
  index.add(1, "Hello World");
  index.add(2, "FlexSearch is amazing!");

Searching the Index

  // Perform a search
  const results = index.search("Hello");
  console.log(results); // [1]

Using FlexSearch with Configurations

  // Create an index with configurations
  const index = new flexsearch.Index({
      tokenize: "forward",
      cache: true,
      context: true
  });

  index.add(1, "Hello World");
  index.add(2, "Welcome to the FlexSearch tutorial");
  index.add(3, "FlexSearch offers great flexibility and performance");

  // Search with context
  const results_with_context = index.search("FlexSearch", { suggest: true });
  console.log(results_with_context);

Implementing FlexSearch in a Simple App

  const flexsearch = require("flexsearch");

  // Create an index
  const index = new flexsearch.Index();

  // Sample data
  const data = [
      { id: 1, content: "Hello World" },
      { id: 2, content: "FlexSearch is amazing!" },
      { id: 3, content: "Fast and efficient text search" },
      { id: 4, content: "Get started with FlexSearch today" }
  ];

  // Add data to index
  data.forEach(item => index.add(item.id, item.content));

  // Search function
  function search(query) {
      return index.search(query);
  }

  // Example usage
  const searchResults = search("FlexSearch");
  console.log(searchResults); // Output: [2, 4]

By integrating FlexSearch into your application, you can significantly enhance the text search functionality, making your app more efficient and user-friendly.
