Typesense Java Client ☕ 🔍

Java client library for accessing the HTTP API of Typesense search engine.

Installation

The client is available on Maven central:

dependencies {
    implementation 'org.typesense:typesense-java:1.1.0'
}
<dependency>
    <groupId>org.typesense</groupId>
    <artifactId>typesense-java</artifactId>
    <version>1.1.0</version>
</dependency>
import org.typesense.api.*;
import org.typesense.model.*;
import org.typesense.resources.*;

Usage

Create a new client

List<Node> nodes = new ArrayList<>();
nodes.add(
  new Node(
    "http",       // For Typesense Cloud use https
    "localhost",  // For Typesense Cloud use xxx.a1.typesense.net
    "8108"        // For Typesense Cloud use 443
  )
);

Configuration configuration = new Configuration(nodes, Duration.ofSeconds(2),"<API_KEY>");

Client client = new Client(configuration);

Create a new collection

List<Field> fields = new ArrayList<>();
fields.add(new Field().name("countryName").type(FieldTypes.STRING));
fields.add(new Field().name("capital").type(FieldTypes.STRING));
fields.add(new Field().name("gdp").type(FieldTypes.INT32).facet(true).sort(true));

CollectionSchema collectionSchema = new CollectionSchema();
collectionSchema.name("Countries").fields(fields).defaultSortingField("gdp");

client.collections().create(collectionSchema);

Create a new collection from JSON file

String schemaJson = new String(
    Files.readAllBytes(Paths.get("schema.json")),
    StandardCharsets.UTF_8
);
client.collections().create(schemaJson);

Index a document

Map<String, Object> hmap = new HashMap<>();
hmap.put("countryName","India");
hmap.put("capital","Delhi");
hmap.put("gdp", 10);

client.collections("Countries").documents().create(hmap);

Upserting a document

Map<String, Object> hmap = new HashMap<>();
hmap.put("countryName","India");
hmap.put("capital","Delhi");
hmap.put("gdp", 5);

client.collections("Countries").documents().upsert(hmap);

Import batch of documents

ImportDocumentsParameters queryParameters = new ImportDocumentsParameters();
queryParameters.action("create");

String documentList = "{\"countryName\": \"India\", \"capital\": \"Washington\", \"gdp\": 5215}\n" +
                      "{\"countryName\": \"Iran\", \"capital\": \"London\", \"gdp\": 5215}";
// Import your document as JSONL string from a file.
client.collections("Countries").documents().import_(documentList, queryParameters)

Search in a collection

SearchParameters searchParameters = new SearchParameters()
                                        .q("tokoyo")
                                        .queryBy("countryName,capital")
                                        .prefix("true,false");
SearchResult searchResult = client.collections("Countries").documents().search(searchParameters);

Update a document

Map<String, Object> hmap = new HashMap<>();
hmap.put("gdp", 8);
client.collections("Countries").documents("28").update(hmap);

Retrieve a document

client.collections("Countries").documents("28").retrieve();

Delete a document

client.collections("Countries").documents("28").delete();

Delete documents using query

DeleteDocumentsParameters deleteDocumentsParameters = new DeleteDocumentsParameters();
deleteDocumentsParameters.filterBy("gdp:=[2,8]");
deleteDocumentsParameters.batchSize(10);

Retrieve a collection

client.collections("Countries").retrieve();

Retrieve all collections

client.collections().retrieve();

Drop a collection

client.collections("Countries").delete();

Export a collection

        .source(new AnalyticsRuleParametersSource()
                .collections(Arrays.asList("Countries")))
        .destination(new AnalyticsRuleParametersDestination()
                .collection("top_searches")));

client.analytics().rules().create(analyticsRule);

Upsert an analytics rule

AnalyticsRuleUpsertSchema analyticsRule = new AnalyticsRuleUpsertSchema()

                .source(new AnalyticsRuleParametersSource()
                        .collections(Arrays.asList("Countries")))
                .destination(new AnalyticsRuleParametersDestination()
                        .collection("failed_searches")));

client.analytics().rules().upsert("failed-searches", analyticsRule);
