getNeighbors return error

[nevermore3]

Please check the FAQ documentation before raising an issue

Describe the bug (required)

go from "Tony Parker" over like Where $^.player.age > 37 yield $^ as src

Filter $^.player.age > 37  pushdown to storage

getNeighbor's result is

 _vid|_stats|_tag:team:_tag:name|_tag:player:_tag:age:name|_tag:bachelor:_tag:name:speciality|_edge:+like:_dst|_expr|
 "Tony Parker"|__EMPTY__|__EMPTY__|[10,36,"Tony Parker"]|__EMPTY__|__EMPTY__|__EMPTY__|

go from "Tony Parker" over like Where like.likeness > 100 yield $^ as src

Filter like.likeness>100 pushdown to storage

getNeighbor's result is

 _vid|_stats|_tag:team:_tag:name|_tag:player:_tag:age:name|_tag:bachelor:_tag:name:speciality|_edge:+like:_dst|_expr|
 "Tony Parker"|__EMPTY__|__EMPTY__|[10,36,"Tony Parker"]|__EMPTY__|__EMPTY__|__EMPTY__|

There will be an error when taking the vertex (should not be return)

Expect
go from "Tony Parker" over like Where $^.player.age > 36 yield $^ as src

getNeighbor's result is

 _vid|_stats|_tag:team:_tag:name|_tag:player:_tag:age:name|_tag:bachelor:_tag:name:speciality|_edge:+like:_dst|_expr|

Expected behavior

Additional context

[critical27]

Em... GetNeighbors's filter is designed for edge's filter only at the first time...

go from "Tony Parker" over like Where $^.player.age > 37 yield $^ as src

We could fix it in storage indeed. But how do we handle an expression when contains both tag and edge?

I think there is a way which won't introduce too much changes: only push down edge's filter...

[nevermore3]

Logically, we should distinguish whether the tag is not satisfied the condition or the edge is not satisfied the condition, if the tag is not satisfied return nothing else return a record
