MultiField Query

[Rod.Madden]

I am using Lucene 2.0 and trying to use the MultiFieldQueryParser 
in my search.
 
I want to limit my search to documents which have "silly"
in "field1" ...within that subset of documents, I want documents which
have
"example" in "field2" OR "field3"
 
The code fragment below is my attempt at this ...code blows
on the : Query query = qp.parse(... 
statement ...
 
Besides blowing, I believe that the MUST / MUST for field2 and field3
is inappropriate ...I really want to say ..if field1 has "silly"
return documents with "example" in field2 OR field3.
 

Any suggestions for accomplishing this ? 
 
Someone suggested BooleanQuery but I was not sure how to merge
that concept in with the MultiFieldQueryParser ..

if (fsDir != null) {
 
 IndexSearcher is = new IndexSearcher(fsDir);
 MultiFieldQueryParser qp == new MultiFieldQueryParser(searchFields,new
StopAnalyzer());
 
 // Is a Lucene IndexSearcher object available
 
 if (qp != null) {
  
     String [] searchTerms   = {"silly",  "example"};             //
search terms
     String [] searchFields  = {"field1", "field2", "field3"};    //
search field names
 
     //   silly MUST occur in field1 - example SHOULD occur in field2
     BooleanClause.Occur [] booleanClauses = 
                             { BooleanClause.Occur.MUST,    
                               BooleanClause.Occur.MUST,
                               BooleanClause.Occur.MUST};
 
     Query query = qp.parse(searchTerms, searchFields, booleanClauses,
new StopAnalyzer());
 
     is.search(query);
 
 
Thanks
