When I try this ( using Lucene 2.0 API ) I get the error:
"..The method parse(String) is not applicable for arguments (String,
String, StopAnalyzer)

When I try this I get the error:
The method add(TermQuery, BooleanClause.Occur) is undefined for type
Query
Could this be a 2.0 issue ?

I can think of two ways to do what you want, one with a parsed query and
one without. With a parsed query:
Query q = QueryParser.parse("+field1:silly +(field2:example
field3:example)",
"field1", new StopAnalyzer());
If you already know the exact structure of the query, then you can just
build it up yourself, i.e. without the QueryParser, like so:
TermQuery t1 = new TermQuery(new Term("field1", "silly")); TermQuery t2
= new TermQuery(new Term("field2", "example")); TermQuery t3 = new
TermQuery(new Term("field3", "example")); Query subq = new
BooleanQuery(); subq.add(t2, BooleanClause.Occur.Should); subq.add(t3,
BooleanClause.Occur.Should); Query q = new BooleanQuery();
q.add(t1, BooleanClause.Occur.MUST);
q.add(subq, BooleanClause.Occur.MUST);
Good luck!
