Subject [jira] [Commented] (LUCENE-4835) Raise maxClauseCount in BooleanQuery to Integer.MAX_VALUE
Date Fri, 15 Mar 2013 20:56:13 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4835?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13603841#comment-13603841

Robert Muir commented on LUCENE-4835:
-------------------------------------

I'm not sure it should be Integer.MAX_VALUE. you can't even create arrays this big with current
jvms. this wouldn't be a safe change. it would change the natural of help requests from "why
did i get TooManyClauses exception" to "why did i get super-strange exception: is this a bug?"

> Discussion on SOLR-4586 raised the idea of raising the limit on boolean clauses from
1024 to Integer.MAX_VALUE.  This should be a safe change.  It will change the nature of help
requests from "Why can't I do 2000 clauses?" to "Why is my 5000-clause query slow?"
