Artifacts:

1. indextank-engine-1.0.0.jar <-- core library

Maven:

groupId: com.flaptor.indextank

artifactId: indextank-engine

version: 1.0.0

Package generation:

Build a single jar containing all dependencies by:

$ mvn package assembly:single

This will create a single file in:

target/indextank-engine-1.0.0-jar-with-dependencies.jar

Quick start with the standalone REST API

You can try basic indexing and searching

Main class: com.flaptor.indextank.api.Launcher

After running the package generation:

$ java -cp target/indextank-engine-1.0.0-jar-with-dependencies.jar com.flaptor.indextank.api.Launcher

This command starts an API server (http://www.indextank.com/documentation/api) at port 20220. The indexing and searching can be done with any client or for example, via curl:

$ curl -d "{\"docid\":\"post1\", \"fields\":{\"text\":\"I love Fallout\"}}" -v -X PUT http://localhost:20220/v1/indexes/idx/docs

$ curl -d "{\"docid\":\"post2\", \"fields\":{\"text\":\"I love Planescape\"}}" -v -X PUT http://localhost:20220/v1/indexes/idx/docs

$ curl http://localhost:20220/v1/indexes/idx/search?q=love
