Description

1.Created a tag super_tag .
2.Created a tag child_tag with superType as super_tag.
3.Associated an entity to child_tag.
4.Basic query :

http://localhost:21000/api/atlas/v2/search/basic?typeName=hdfs_path&classification=child_tag
http://localhost:21000/api/atlas/v2/search/basic?typeName=hdfs_path&classification=super_tag

Both returned the entity.

DSL search :

http://localhost:21000/api/atlas/v2/search/dsl?typeName=hdfs_path&classification=child_tag

returned the correct entity.

whereas

http://localhost:21000/api/atlas/v2/search/dsl?typeName=hdfs_path&classification=super_tag

returned 0 results.

Following log is found in application.log for the DSL Search of tags.

 WARN  - [pool-1-thread-10 - 51ba13c9-493c-4c62-b11c-a8513ba771e9:] ~ Found non-extractable argument '_().out('super_tag')' in the 'and' expression 'g.V().or(has('__typeName','hdfs_path'),has('__superTypeNames','hdfs_path')).as('a0').and(_().out('super_tag'))' (ExpandAndsOptimization:111)

The above log is not specific to search with parent tag. Such log is printed for search with child tags also.
