Description

It would be nice if a search on a complex entity could perform a search on attributes of nested sub-entities or structs, as well as just top-level attributes.  

Here is an example of an Atlas basic search request object:
{
"typeName": "hive_table",
"excludeDeletedEntities": true,
"classification" : "",
"query": "",
"limit": 25,
"offset": 0,
"entityFilters":

{ "attributeName": "name", "operator": "contains", "attributeValue": "testtable" }

,
"tagFilters": null,
"attributes": [""]
}

Here, attributeName must be one of the top-level attributes of the hive table entity.

This ticket requests that path expressions to attributes of sub-entities or structs also be allowed as attributeNames, eg column.name  (similar to DSL search).   This would execute a search on the name attribute of columns that are associated with the hive table.
