But if someone searches for "radiotherapy", I want content with that to rank higher than content with "radiation". Will Payloads do this for me? I would try it but I'm having trouble figuring out how to do the search. For the search, I'm currently using a MultiFieldQueryParser, so like this: SnowballAnalyzer sba = new SnowballAnalyzer("English", StopAnalyzer.ENGLISH_STOP_WORDS); QueryParser qp = new MultiFieldQueryParser( new String[] {"field1", "field2", "field3"}, sba ); try { Query query = qp.parse(strSearchTerms); } catch ( Throwable th) { ... } However, the payload example in the presentation requires a BoostingTermQuery, like this: Query query = new BoostingTermQuery( new Term(“field”, “searchterm”)); Is there a way to make the two work together? Thanks!
