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

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:"test@yahoo.cn"},{_id:"P002",_uuid:2,age:27,email:"test@ultipa.com"}])
insert().into(@student).nodes([{_id:"S001",_uuid:3,age:27,email:"test@yeah.net"},{_id:"S002",_uuid:4,age:20,email:"test@w3.org"},{_id:"S003",_uuid:5,age:25,email:"test@gmail.com"}])

Property

Example: Find nodes whose age belongs to [20,25,30,35]

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

|---------------- @student ---------------|
|  _id  | _uuid |  age  |       email     |
|-------|-------|-------|-----------------|
| S002  |   4   |  20   | test@w3.org     |
| S003  |   5   |  25   | test@gmail.com  |

Example: Find nodes of @professor, whose age belongs to [20,25,30,35]

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

No return data

_uuid (Abbreviated)

When a filter only judges whether the _uuid of the current node/edge belongs to a list of integers, the filter can be abbreviated as below：

Example: Find node whose _uuid belongs to [2,3,5]

find().nodes([2,3,5]) as n
return n{*} 

|---------------- @student ---------------|
|  _id  | _uuid |  age  |       email     |
|-------|-------|-------|-----------------|
| S001  |   3   |  27   | test@yeah.net   |
| S002  |   4   |  20   | test@w3.org     |
| S003  |   5   |  25   | test@gmail.com  |
