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

Run below UQLs one by one in an empty graphset to create graph data: ```customlang___fold__lang_uql 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 does not belong to [20,25,30,35]

UQL
find().nodes({age nin [20,25,30,35]}) as n
return n{*} 

Result
|--------------- @professor --------------|
|  _id  | _uuid |  age  |       email     |
|-------|-------|-------|-----------------|
| P001  |   1   |  53   | [email protected]   |
| P002  |   2   |  27   | [email protected] |

|---------------- @student ---------------|
|  _id  | _uuid |  age  |       email     |
|-------|-------|-------|-----------------|
| S001  |   3   |  27   | [email protected]   |

Example: Find nodes of @professor, whose age does not belong to [20,25,30,35]

UQL
find().nodes({@professor.age nin [20,25,30,35]}) as n
return n{*} 

Result
|--------------- @professor --------------|
|  _id  | _uuid |  age  |       email     |
|-------|-------|-------|-----------------|
| P001  |   1   |  53   | [email protected]   |
