Otis Gospodnetic commented on SOLR-756:
---------------------------------------
My colleagues and I have recently hit a similar wall -- DisMax not allowing
wildcards.
I think Hoss will be the loudest (not in a negative sense) here, so here are
some specific questions:
# are we OK with adding wildcard (and other) support to "dismax"?
# if yes, which part of "dismax" should that be added to? (David described the
2 meanings of "dismax")
I've hit this wall a couple of times that I think it's worth thinking about how
to get support for non-plain-keywords-only queries somethere in the DisMax
area. Like David, I too want to make use of the other functionality that
already exists there, such as bf, ps, etc.
Thanks.
> Make DisjunctionMaxQueryParser generally useful by supporting all query types.

> Key: SOLR-756
> URL: https://issues.apache.org/jira/browse/SOLR-756
> Project: Solr
> Issue Type: Improvement
> Affects Versions: 1.3
> Reporter: David Smiley
> Attachments: SolrPluginUtilsDisMax.patch
>
>
> 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)
