this is weird... in your example, you got the member node and piped it into
the next portion, via:
MATCH (me:Member {id: {member_id}})
WITH me, me.birth_year as birth_year
im assuming this is so that the comparison on me.birth_year and
other.birth_year can occur, without having the cross-path comp
Yes, that's true.
cross path meant from different segments of the path.

ah... i think i know what you mean.
that is, that i am comparing me.birth_year, and other.birth_year, both of
which were part of the same path, so splitting it up like you did (via the
WITH me.birth_year) did the trick?

Michael, awesome, thank you.
just to make sure I understand correctly, in this case, when you say 'cross
path comparison',
what are the 2 paths you are referring to?

Michael, I apologize, I will send you a copy of the query + profile too.
In my actual query, I am using a parameter of the cypher query:
WHERE other.birth_year > (me.birth_year - {age_difference_range})
AND other.birth_year < (me.birth_year + {age_difference_range})
here is the relevant prof
Right, cross path comparisons are not yet used to shortcut path-finding
so if you rewrite your query to this, it will actually filter down the paths
eagerly
MATCH (me:Member {id: 11700})
WITH me, me.birth_year as birth_year

You will notice:
"WHERE (Property(NodeIdentifier(),cached_available(71)) == Literal(1)" in
the TraversalMatcher() portion, the very first function of the profile..
I believe that this is what is meant when the documentation says that the
WHERE clause is not done after, (therefore during) the mat
Mark, I have emailed you the query and profile for both cases.

The problem is cross-path expressions, which are not yet handled in that manner
for simple expressions that only contain a single piece of the path (node, rel)
and things that have been evaluated before (parameters, literals, previous
computations) WILL be used to shortcut the path evaluation.
Mark, I would be happy to. Give me a moment and I will post them.

Javad,
Can you paste the PROFILE output for the two queries on here. In theory the
two queries should do the same thing...in practice I imagine that's not the
case!
