How to output append reason to similarities in Gremlin

Vote count:

0

I have the following simple Graph:

User -- Likes --> Item

I'm finding top 10 similar users to a user u using the following Gremlin code:

u.out('Likes').in('Likes').filter([u]).groupCount.cap.orderMap(T.decr)[0..10].map()

This outputs something like that:

==>{userid=1}
==>{userid=5}
==>{userid=10}
==>{userid=15}

I would like the output to be more informative and have additional information such as rank in the sorted map and items (itemid) shared with the original user, something like this:

==>{userid=1, rank=0, reason_items={1,2,3,5}}
==>{userid=5, rank=1, reason_items={1,2,10}}
==>{userid=10, rank=2, reason_items={1,2,4}}
==>{userid=15, rank=3, reason_items={1,2}}

An efficient gremlin-groovy code sample would be nice!

Thank you.
