Update on my code:
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 {
IndexReader reader;
try {
reader = IndexReader.open(FSDirectory.open(new
File("C:\\java\\apache-solr-4.0.0\\apache-solr-4.0.0\\example\\solr\\Books\\data\\index")));
IndexSearcher searcher = new IndexSearcher(reader);
BooleanQuery fromQuery = new BooleanQuery();
fromQuery.add(new TermQuery(new Term("pageTxt", "crazy")),
BooleanClause.Occur.MUST);
fromQuery.add(new TermQuery(new Term("pageTxt", "test")),
BooleanClause.Occur.SHOULD);
return JoinUtil.createJoinQuery("pageId", true,
"fileId",fromQuery, searcher, ScoreMode.Avg);
} catch (IOException ex) {
Logger.getLogger(TestParserPlugin.class.getName()).log(Level.SEVERE, null, ex);
}
return null;
}
}
}
I still have 2 questions concerning this code:
Is there a way to get the searcher instead of opening from fs everytime I use
this plugin?(I think this will create a memory leak)
Is it possible to combine this qparser with edismax etc in stead of building
queries using occur.must etc...
