Thanks for you response. By ' If you tell Janus about the indexed properties using the management API' you mean, creating property keys and index using management API right ?

If you tell Janus about the indexed properties using the management API it will use them automatically when you run Gremlin queries. You only need to use indexQuery for cases where you want to read from the index directly for other reasons.

Hi,

I am using Janusgraph with ES as index backend. I created a mixed index  on some vertex attributes. This mixed index is saved in ES.

Now if i query for that vertices based on index, will janusgraph use ES internally to perform search operation ? Or do i need to use IndexQuery to perform search on ES directly ?
