I'm trying to figure out how I can use the JoinUtil class in the plugin. I've already added
it to my config and it seems to get registered. But I can't figure out how to get the indexSearcher
in the TestParser? I know I'm using a predefined query. 

I also get an errormessage saying:
"java.lang.RuntimeException: java.lang.NoClassDefFoundError: org/apache/lucene/search/join/ScoreMode"
I've added the lucene libs and that solved this errormessage. Is it normal solr does not contain
all lucene libraries?


This is the code I'm using.

See the next post for update!

public class TestParserPlugin extends QParserPlugin {

    @Override
    public QParser createParser(String string, SolrParams sp, SolrParams sp1, SolrQueryRequest
sqr) {
        return new TestParser(string, sp1, sp1, sqr);
    }

    @Override
    public void init(NamedList nl) {
        
    }
 
    public class TestParser extends QParser{

        public TestParser(String qstr, SolrParams localParams, SolrParams params, SolrQueryRequest
req) {
            super(qstr, localParams, params, req);
        }

        
        
        @Override
        public org.apache.lucene.search.Query parse() throws org.apache.lucene.queryparser.classic.ParseException
{
            try {
                return JoinUtil.createJoinQuery("pageId", true, "fileId", new Query() {

                    @Override
                    public String toString(String string) {
                       return "pageTxt:test";
                    }
                }, null, ScoreMode.Avg);//the null is the parameter I don't know how to get
in the parser!
            } catch (IOException ex) {
                Logger.getLogger(TestParserPlugin.class.getName()).log(Level.SEVERE, null,
ex);
            }
            return null;
        }
    }
}
