Text Search

Use the $text operator to perform text searches on fields which have a text index.

To create a text index on a collection, pass a document containing the name of the field to be indexed with the value ‘text’ to the createIndex() method.

function createTextIndex(db, callback) {
 // Get the restaurants collection
 const collection = db.collection('restaurants');
 // Create the index
 collection.createIndex(
 { name : "text" }, function(err, result) {
 console.log(result);
 callback(result);
 });
};
const MongoClient = require('mongodb').MongoClient;
const assert = require('assert');
// Connection URL
const url = 'mongodb://localhost:27017';
// Database Name
const dbName = 'myproject';
// Use connect method to connect to the Server
MongoClient.connect(url, function(err, client) {
 assert.equal(null, err);
 console.log("Connected correctly to server");
 const db = client.db(dbName);
 createTextIndex(db, function() {
 client.close();
 });
});

The following example assumes that a database called test has a collection called restaurants, with a text index on the name field. A sample dataset is available for download.

function findDocuments(db, callback) {
 // Get the documents collection
 const collection = db.collection('restaurants');
 // Find some documents
 collection.find({ '$text': {'$search' : 'Garden' } } ).toArray(function(err, docs) {
 assert.equal(err, null);
 console.log("Found the following records");
 console.log(docs);
 callback(docs);
 });
}
// use the findDocuments() function
const MongoClient = require('mongodb').MongoClient;
const assert = require('assert');
// Connection URL
const url = 'mongodb://localhost:27017';
// Database Name
const dbName = 'myproject';
// Use connect method to connect to the Server
MongoClient.connect(url, function(err, client) {
 assert.equal(null, err);
 console.log("Connected correctly to server");
 const db = client.db(dbName);
 findDocuments(db, function() {
 client.close();
 });
});
