Atlas Search makes it easy to build fast, relevance-based search capabilities on top of your MongoDB data. Try it today on MongoDB Atlas, our fully managed database as a service.

Alternatively, MongoDB supports simpler query operations that perform a text search of string content. To perform text search, MongoDB uses a text index and the $text query operator.

The Java driver provides the Filters.text() helper to facilitate the creation of text search query filters.


  • The example below requires a restaurants collection in the test database. To create and populate the collection, follow the directions in github.

  • Include the following import statements:

     import com.mongodb.client.MongoClients;
     import com.mongodb.client.MongoClient;
     import com.mongodb.client.MongoCollection;
     import com.mongodb.client.MongoDatabase;
     import com.mongodb.client.model.Indexes;
     import com.mongodb.client.model.Filters;
     import com.mongodb.client.model.Sorts;
     import com.mongodb.client.model.TextSearchOptions;
     import com.mongodb.client.model.Projections;
     import org.bson.Document;

Connect to a MongoDB Deployment

Connect to a MongoDB deployment and declare and define a MongoDatabase instance.

For example, include the following code to connect to a standalone MongoDB deployment running on localhost on port 27017 and define database to refer to the test database:

MongoClient mongoClient = MongoClients.create();
MongoDatabase database = mongoClient.getDatabase("test");

For additional information on connecting to MongoDB, see Connect to MongoDB.

Create the text Index

To create a text index, use the Indexes.text static helper to create a specification for a text index and pass to MongoCollection.createIndex() method.

The following example creates a text index on the name field for the restaurants collection.

MongoCollection<Document> collection = database.getCollection("restaurants");

To perform text search, use the Filters.text() helper to specify the text search query filter.

For example, the following code performs a text search on the name field for the word "bakery" or "coffee".

long matchCount = collection.countDocuments(Filters.text("bakery coffee"));
System.out.println("Text search matches: " + matchCount);

The example should print the following output:

Text search matches: 2

For more information on the text search, see $text operator.

Text Score

For each matching document, text search assigns a score, representing the relevance of a document to the specified text search query filter. To return and sort by score, use the $meta operator in the projection document and the sort expression.

collection.find(Filters.text("bakery cafe"))
                       .forEach(doc -> System.out.println(doc.toJson()));

Specify a Text Search Option

The Filters.text() helper can accept various text search options. The Java driver provides TextSearchOptions class to specify these options.

For example, the following text search specifies the text search language option when performing text search for the word cafe:

long matchCountEnglish = collection.countDocuments(Filters.text("cafe", new TextSearchOptions().language("english")));
System.out.println("Text search matches (english): " + matchCountEnglish);

The example should print the following output:

Text search matches (english): 1
