Filters based on a predicate, a sideEffect or a traversal.
Synopsis
where()
Description
The where() step is a filter step that filters the returned objects based on a predicate, a sideEffect, or a traversal.
Examples
First find all the reviewers that rated Beef Bourguignon 5-stars.
Then find what other recipes those reviewers rated 5-stars, and count how many reviewers did by recipe, without including Beef Bourguignon in the count.
It illustrates the use of the where() step with where(neq('a')) to exclude Beef Bourguignon.
g.V().has('recipe', 'name', 'Beef Bourguignon').as('a').
inE('reviewed').has('stars', 5).outV().outE('reviewed').has('stars', 5).
inV().where(neq('a')).groupCount().by('name')
