-------------------------------------------------------------------------
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 {

SolrQueryRequest sqr) {
return new TestParser(string, sp1, sp1, sqr);

}
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;
}
}
}
