It relies on its own query engine.
Oak provides, 4 main index types: traverse, property, lucene and solr. If no index is defined, or no one is suitable for the provided query, the Traverse will come to play. It's a built-in index always there that will traverse the repository in search for the content complying with the query you provided. You define the index you need. Please read my previous email where I explained in more details the "doesn't index anything" aspect as well as the docs around the query engine. They may not explain how the query engine works but provides enough details for not having to read the code http://markmail.org/message/wvq7ggu737ex277b http://jackrabbit.apache.org/oak/docs/query/query.html > b.

I'd go for lucene if you don't need any solr specific feature. You'll need to define your own index. You can find details in the docs http://jackrabbit.apache.org/oak/docs/query/query.html HTH Davide
