Stephen Mallette closed TINKERPOP-2923.
---------------------------------------
Resolution: Not A Bug
> Connected predicates with where() not returning results
> -------------------------------------------------------
>
> Key: TINKERPOP-2923
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2923
> Project: TinkerPop
> Issue Type: Bug
> Components: process
> Affects Versions: 3.5.5
> Reporter: Stephen Mallette
> Priority: Minor
>
> There may be nothing wrong here, but I couldn't get this to work so needs
> some investigation. I unfortunately didn't have time for a more simple
> example. Given:
> {code}
> g.addV('Question').
> as('40964128').
> property(single, 'code', "0004").
> property(single, 'difficultyInPattern', 4).
> property(single, 'pattern', "適語補充").
> addV('Question').
> as('40968224').
> property(single, 'code', "0005").
> property(single, 'difficultyInPattern', 5).
> property(single, 'pattern', "適語補充").
> addV('LearningElement').
> as('40972320').
> property(single, 'name', "ダミー学習要素").
> addV('Question').
> as('4144').
> property(single, 'code', "0006").
> property(single, 'difficultyInPattern', 1).
> property(single, 'pattern', "記述").
> addV('Question').
> as('8240').
> property(single, 'code', "0010").
> property(single, 'difficultyInPattern', 5).

> It currently returns no results so it's over-filtering for some reason.
> Perhaps has some connection to {{gt}} because even this doesn't work:
> {code}
> g.V().has('Question','code','0003').as('a').
> out('has').in('has').as('b').
> where('b', neq('a')).
> where('b', eq('a').and(gt('a'))).

> bothE()
