Spring Data for Apache Solr Extended DisMax Parameters

I am trying to add the params below (qf,bq) in a Solr query generated by Spring Data Solr.

Solr parameters are :

qf => Spring Data Solr Method?
bq => Spring Data Solr Method?

I was able to find the methods below

fq => addFilterQuery
fl => addProjectionOnField
defType => setDefType
qt => setRequestHandler

I saw an open issue qf https://jira.spring.io/browse/DATASOLR-153

How can i add the qf and bq params to Solr query built with Spring Data Solr.

Thanks

You can use the SolrCallback on template level to access the SolrClient and execute the query from there or register your own QueryParser for a custom query type.

Maybe something like:

@Bean
public SolrTemplate solrTemplate(SolrClient client) {

    SolrTemplate template = new SolrTemplate(client);
    template.registerQueryParser(EdismaxQuery.class, new EdisMaxQueryParser());
    return template;
}

class EdismaxQuery extends SimpleQuery {
    // ... add stuff you need. Maybe `autoRelax`
}

class EdisMaxQueryParser extends QueryParserBase<EdismaxQuery> {

    DefaultQueryParser defaultQueryParser = new DefaultQueryParser();

    @Override
    public SolrQuery doConstructSolrQuery(EdismaxQuery source) {

        // just use the default parser to construct the query string in first place.
        SolrQuery target = defaultQueryParser.constructSolrQuery(source);

        // add missing parameters
        target.add("defType", "edismax");
        target.add("qf", source....);

        return target;
    }
}
