> SOLR-839 added XML QueryParser support (deftype=xmlparser) and this ticket here proposes
to make that support extensible-via-configuration.
> Objective:
>  * To support use of custom query builders.
>  * To support use of custom query builders _without_ a corresponding custom XmlQParser
plugin class.
> Illustration:
>  * solrconfig.xml snippet to configure use of the custom builders
> {code}
> <queryParser name="testxmlparser" class="XmlQParserPlugin">
>   <str name="HelloQuery">org.apache.solr.search.HelloQueryBuilder</str>
>   <str name="GoodbyeQuery">org.apache.solr.search.GoodbyeQueryBuilder</str>
> </queryParser>
> {code}
> * HelloQueryBuilder and GoodbyeQueryBuilder both extend the new abstract SolrQueryBuilder
class.
> {code}
> + public abstract class SolrQueryBuilder implements QueryBuilder {
> +   protected final SolrQueryRequest req;
> +   protected final QueryBuilder queryFactory;
> +   public SolrQueryBuilder(String defaultField, Analyzer analyzer,
> +       SolrQueryRequest req, QueryBuilder queryFactory) {
> +     this.req = req;
> +     this.queryFactory = queryFactory;
> +   }
> + }
> {code}
