*Glossary Term based filtering:*

- In order to retrieve entities based on glossary term, a query would use hasTerm keyword.
- To get entities with associated glossary term, user needs to add fully qualified name. i.e {termName}@{glossaryName}
- In case user adds only term name, all the entities associated with term name will return, irrespective of, to which glossary it is in.

Example: To retrieve all entities of type Table having glossary

from Table hasTerm "modernTrade@salesGlossary",
Table hasTerm "modernTrade@salesGlossary",
Table hasTerm "modernTrade",
Table where Table hasTerm "modernTrade@salesGlossary",
Table hasTerm "modernTrade@salesGlossary" and db.name = "sales"
