[jira] Commented: (SOLR-334) pluggable query parsers

["Yonik Seeley (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-334?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12525195 ] 

Yonik Seeley commented on SOLR-334:
-----------------------------------

could be a way to mostly unify what are currently different request handlers and parameters

<!dismax>the user query goes here
<!function>recip(rord(datefield),1,2,3)

Optionally, dismax we could perhaps allow selective overriding of the dismax params
<!dismax mm=".5">another dismax query
This would allow any query handler that needed to specify more than one query to be able to use more than one dismax query.

> One should be able to optionally specify an alternate query syntax on a per-query basis

> Many benefits, including avoiding the need to do query parser escaping for simple term or prefix queries.
> Possible Examples:
> fq=<!term field="myfield">The Term
> fq=<!prefix field="myfield">The Prefix
> q=<!qp op="AND">a b
> q=<!xml><?xml...>  // lucene XML query syntax?
