A tiny search engine.
Suitable for in-browser use, this provides n-gram based search results.
import { SearchEngine } from '@toastdriven/nanosearch';
// Create a search engine.
const engine = new SearchEngine();
// Index some documents.
// First parameter is the unique document ID, second is the document text.
engine.add("abc", "The dog is a 'hot dog'.");
engine.add("def", "Dogs > Cats");
engine.add("ghi", "the quick brown fox jumps over the lazy dog");
engine.add("jkl", "Am I lazy, or just work smart?");
// Then, you can let the user search on the engine...
let myDogResults = engine.search("my dog");
myDogResults.count(); // 3
for(let res of myDogResults.iterator()) {
console.log(res.docId); // ex: "def"
console.log(res.score); // ex: 0.2727272727272727
}
// ...including limiting results (to just one)...
let lazyResults = engine.search("lazy");
let topResult = lazyResults.at(0);
console.log(topResult);
// ...or making pages of ten results!
let dogResults = engine.search("dogs");
let pageOne = dogResults.slice(0, 10);
let pageTwo = dogResults.slice(10, 20);
console.log(pageOne);
console.log(pageTwo);$ npm install @toastdriven/nanosearch
