Exposing traversal depth from MATCH

[leo...@kensho.com]

Hi.

Is there any way of exposing $depth context variable from the MATCH statement to the result consumer.

E.g. in the documentation example I'd like to get the actual degree of separation between a pair of people (I don't care which path) as part of the output. 

Thanks

$depth is used in while condition, so you define it.

Are you looking for shortest/longest path?

If you are using MATCH you can't return $depth, as workaroud you can use it with select:

SELECT @rid,$depth FROM (TRAVERSE * FROM V)

If you need to use it with MATCH you can open a request on github.
