I think we need to spin 2.9.1 for this.

>             Project: Lucene - Java
>          Issue Type: Bug
>          Components: Query/Scoring
>    Affects Versions: 2.9
>            Reporter: tangfulin
>            Assignee: Michael McCandless
>             Fix For: 2.9.1, 3.0

> query: (name:tang*)
> doc=5137 score=1.0  doc:Document<stored,indexed<name:tangfulin>>
> doc=11377 score=1.0  doc:Document<stored,indexed<name:tangfulin>>
> query: name:tang* name:notexistnames
> doc=5137 score=0.048133932  doc:Document<stored,indexed<name:tangfulin>>
> It is two queries on the same index, one is just a prefix query in a
> boolean query, and the other is a prefix query plus a term query in a
> boolean query, all with Occur.SHOULD .
> what I wonder is why the later query can not find the doc=11377 doc ?
> the problem can be repreduced by the code in the attachment .
