> Backport: Basic search issue with IndexSerializer
> -------------------------------------------------
>
> Key: ATLAS-3816
> URL: https://issues.apache.org/jira/browse/ATLAS-3816
> Project: Atlas
> Issue Type: Bug
> Affects Versions: 0.8.4
> Reporter: Nikhil Bonte
> Assignee: Nikhil Bonte
> Priority: Major
> Fix For: 0.8.4
>
> Attachments:
> ATLAS-3816-Backport-Basic-search-issue-with-IndexSer-v2.patch
>
>
> *Background:*
> Atlas instance with property
> _"atlas.use.index.query.to.find.entity.by.unique.attributes=true"_
> Direct index query which has pattern *"v."* throws exception, e.g.
>
> v."Referenceable.qualifiedName":"atscale_agg_in{color:#ff0000}v.{color}as_agg_2cfb287d_dal_fixed_inco@edldev"
>
> This will throw
> {code:java}
> java.lang.IllegalArgumentException: Found reference to non-existant property
> key in query at position...{code}
>
> *Solution:*
> Backporting ATLAS-2371.
> It is resolved with janusgraph, for titan implementation backporting required.
> Query will be :
> *$v$*"Referenceable.qualifiedName":"atscale_agg_in{color:#ff0000}v.{color}as_agg_2cfb287d_dal_fixed_inco@edldev"
>
> Default value for index search prefix is _"$v$"_
> Can be changed using the property _"atlas.graph.index.search.vertex.prefix"_
>
