David Smiley commented on SOLR-756:
-----------------------------------
Jan, you refer to the Extended Dismax QParser -- and the answer is no. I think
you intended to comment on SOLR-758. This patch here, as I said in a comment
above here
https://issues.apache.org/jira/browse/SOLR-756?focusedCommentId=12630223&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-12630223
only has to do with a specific improvement to SolrPluginUtils.java, that is an
enabler for other improvements to DismaxQParser. According to Hoss, I need to
add tests for this issue.
> Make DisjunctionMaxQueryParser generally useful by supporting all query types.

>
> This is an enhancement to the DisjunctionMaxQueryParser to work on all the
> query variants such as wildcard, prefix, and fuzzy queries, and to support
> working in "AND" scenarios that are not processed by the min-should-match
> DisMax QParser. This was not in Solr already because DisMax was only used for
> a very limited syntax that didn't use those features. In my opinion, this
> makes a more suitable base parser for general use because unlike the
> Lucene/Solr parser, this one supports multiple default fields whereas other
> ones (say Yonik's {!prefix} one for example, can't do dismax). The notion of
> a single default field is antiquated and a technical under-the-hood detail of
> Lucene that I think Solr should shield the user from by on-the-fly using a
> DisMax when multiple fields are used.
> (patch to be attached soon)
