Subject [jira] [Commented] (SOLR-3823) Parentheses in a boost query cause errors
Date Wed, 12 Sep 2012 15:19:07 GMT

    [ https://issues.apache.org/jira/browse/SOLR-3823?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13454059#comment-13454059

Erick Erickson commented on SOLR-3823:
--------------------------------------

James:

The problem was quite the opposite. When there was NO space in the bq clause it'd fail like
this, i.e.
bq=(stuff). And when there was space, I don't think it worked at all....

But yeah, it'd be good to have both parens and negative boosts...

> When using a boost query (bq) that contains a parentheses (like this example from the
Relevancy Cookbook section of the wiki):
> {noformat}
>  ? defType = dismax 
>     & q = foo bar 
>     & bq = (*:* -xxx)^999 
> {noformat}
> You get the following error:
> org.apache.lucene.queryparser.classic.ParseException: Cannot parse '-xxx)': Encountered
