Hi Björn,
yes, the error you point out will happen indeed... A possible
workaround would be:
public Hits search(String queryString, int numHits,
String dedupField, String sortField, boolean reverse)
throws IOException {
org.apache.lucene.queryParser.QueryParser parser = new
org.apache.lucene.queryParser.QueryParser("content", new
org.apache.lucene.analysis.standard.StandardAnalyzer());
org.apache.lucene.search.Query luceneQuery = null;
try {
luceneQuery = parser.parse(queryString);
} catch(Exception ex) {
}
org.apache.lucene.search.BooleanQuery boolQuery = new
org.apache.lucene.search.BooleanQuery();
boolQuery.add(luceneQuery,
org.apache.lucene.search.BooleanClause.Occur.MUST);
return translateHits
(optimizer.optimize(boolQuery, luceneSearcher, numHits,
sortField, reverse),
dedupField, sortField);
}
Please notice that I'm not sure this will work as it should: right
now, it just compiles... I still need to modify the NutchBean class so
it can pass on the raw query, as Ravi says.
Regards,
Cristina

This seems to be a good approach. I have not yet tried it out in
detail, however, the method optimize() in LuceneQueryOptimizer does
only take BooleanQuery as an argument, so the line 'return
translateHits...' would cause a compile error, wouldn't it?
