Hello, I have a data structure such as:
(vertex) [edge]

(user) -> [access] -> (target)
and
(user) -> [access] -> (group) -> [access] -> (target)

I want to retreive the [access].@rid closest to the user (farthest left in 
the diagram) knowing the (user).@rid and (target).@rid


I thought I could create this query by trial and error and looking at the 
results, so I start with
select from access where in = #13:8 and out = #12:17
This finds the first case only

So If i query
select expand(in.out(access)) from access where out = #12:17
I can see that the result is the (target) I am trying to link to at #13:8

So my instinct is to try
select from access where out = #12:17 and in.out(access).@rid = #13:8


What is the fundamental thing I am misunderstanding? Can you not do in.out 
in a where clause? I feel like the manual has not really taught me how to 
write such a query with traverse or LET or otherwise.

Is there any other resources which walks through creating complex queries?

Thanks for your time.
