Your answer is quite clear, but my question is a bit more specific: as you seen from my snippet ( I copy it here again), I'm already using BooleanQuery and QueryParser.parse method.
booleanQuery.add(new QueryParser(org.apache.lucene.util.Version.LUCENE_40, "tags", new WhitespaceAnalyzer(org.apache.lucene.util.Version.LUCENE_40)).parse(phrase[i]); , BooleanClause.Occur.SHOULD); I'm however wondering if this is correct way to pass single terms to booleanQuery. QueryParser.parse method returns a SrndQuery object, which I directly passing to booleanQuery.add. Not sure if this is correct. Should I extract single terms instead from SrndQuery... or something like that, and invoke booleanQuery.add several times ? thanks On 22 March 2011 14:27, Erick Erickson <erickerick...@gmail.com> wrote: > A good habit to develop is to print out the toString() of the assembled > queries, that'll get you going pretty quickly understanding what the > query assembly is all about without having to wait for people to respond. > > But the short form is that phrase queries require all the terms to be > adjacent, which may be what you want but may not. > > BooleanQuery is just asking for all the terms.
