We faced with performance issue on our project when sorting and counting hundreds of thousands of vertices by different vertex properties and existance of relationships between them.
To solve the issue we decided to denormalize our data, index all sorting and filtering properties in solr and use 'direct index queries'. However we didn't find a way, how to use those indices for sorting via indexQuery(). Also it was impossible to get 'response.numFound' from solr results to return total number of results to user.
My branch contains required changes, which allow us to sort blazingly fast on the solr side via titan. We are able to return total number of results satisfying the search query as well.
