Is there a limit to how much can be passed back here? Can the user run a
request that returns too much data?
Do we need paging? Max return count?

> Key: METRON-1022
> URL: https://issues.apache.org/jira/browse/METRON-1022
> Project: Metron
> Issue Type: New Feature
> Reporter: Ryan Merriman
>
> We need a "search" endpoint that will allow basic lucene-style searches with
> sorting and pagination options. This endpoint should have a light
> abstraction on top to make it simpler to consume and possibly allow different
> search engines to be used in the future.
