> When I do a discovery/search/gremlin?query I can either specify my starting node with
the titan id , query=g.v(id).... or if I don't have it I can use g.V.has('Referenceable.qualifiedName','id')....
The first takes about 200ms and the second takes roughly two seconds (timed in chrome dev
tools) . As such, I would like to get the titan id when I fetch an entity so that later queries
takes a reasonable amount of time. 
> Alternatively, the search documentation must be updated with loop-query examples so I
can use the DSL instead. The technical user guide doesn't even mention Gremlin, so I am not
sure if it is supposed to be used or not. Since the web has many good Gremlin tutorials and
no Atlas DSL tutorials I would prefer to use Gremlin. 
> As a use case, I have one time series entity that is updated daily with new values from
csv-files. The lineage shows n CSV files, n import_job entities and one timeseries, and i
would like to know which CSV-file is the source of a range of my timeseries.
