[jira] Issue Comment Edited: (LUCENE-25) QueryParser produces empty
BooleanQueries when all clauses are stop words
[ https://issues.apache.org/jira/browse/LUCENE-25?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12553215 ]

-----------------------------------------------------------------
Attached patch adds a test to QP for this. It now seems like QP is doing reasonable things with stopwords at least for a few cases. Of course, I am not sure what QP should return when all the terms are stopwords (it currently returns a BooleanQuery with zero clauses)
I am not sure when this was fixed.
In other words, I would like to close this.
