Cool!
1. So you are creating a parser with { name, synonyms, propIn }, correct?
2. Sorry -- I meant the output of "query.toString()"; I'm expecting to see
something like this when the sentence parameter is set to philipcimiano:
name:philipcimiano synonyms:philipcimiano propIn:philipcimiano
3. Out of curiosity, what is the value of topDocs.totalHits for your search?
