using EMPTY exception in match statement

[cooper-lzy]

Judging by a nonexistent property, it is said that all points should be returned.
MATCH (v:player) WHERE v.nadsaesa IS EMPTY return v;

This is to determine whether V2 has an age property. Normally, the team point should be filtered out.
MATCH (v:player)--(v2) WHERE v2.age IS NOT EMPTY RETURN labels(v2)

IS NOT EMPTY in where clause is applied to the result. That means the result in the 2nd picture is within our expectations. We could use exists in such a situation.

MATCH ... WHERE exists(v2.age) RETURN labels(v2)
