      Sample graph: (to be used for the following examples)

      Run below UQLs one by one in an empty graphset to create graph data:

      create().node_schema("professor").node_schema("student")
      create().node_property(@*, "age", int32).node_property(@*, "email", string)
      insert().into(@professor).nodes([{_id:"P001",_uuid:1,age:53,email:"[email protected]"},{_id:"P002",_uuid:2,age:27,email:"[email protected]"}])
      insert().into(@student).nodes([{_id:"S001",_uuid:3,age:27,email:"[email protected]"},{_id:"S002",_uuid:4,age:20,email:"[email protected]"},{_id:"S003",_uuid:5,age:25,email:"[email protected]"}])
      

      Property

      Example: Find nodes whose age is greater than 27

      find().nodes({age > 27}) as n
      return n{*} 
      

      |--------------- @professor --------------|

      | P001  |   1   |  53   | [email protected]   |
      

      Example: Find nodes of @professor, whose age is greater than 27

      find().nodes({@professor.age > 27}) as n
      return n{*}
