Subject [jira] Created: (LUCENE-1974) BooleanQuery can not find all matches in special condition
Date Mon, 12 Oct 2009 02:19:31 GMT
BooleanQuery can not find all matches in special condition

                 Key: LUCENE-1974
             Project: Lucene - Java
          Issue Type: Bug
          Components: Query/Scoring
    Affects Versions: 2.9
            Reporter: tangfulin

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 .
