I found the source of error: Turns out that given a query of the form 'Field:(A AND-(B))' (note the no space between 'AND' and '-'), lucene-1.3 would output +Field:a -Field:b, while lucene-1.4 would output Field:a Field:- Field:b
Thanks for all the help and the suggestions.

So there is a change for a-b between 1.3 and 1.4 1.3 gives a -b 1.4 gives "a b" or one token a-b (depending on the analyzer) as it treats the - as part of a word. > > So is this behaviour a bug, or Lucene1.4 is not backwards compatible? > Your behaviour cannot be seen from the test code (as Daniel already said): java -cp lucene-1.3-final/lucene-1.3-final.jar org.apache.lucene.queryParser.QueryParser 'Field:(A AND -(B))' +Field:a -Field:b java -cp lucene-1.4-final/lucene-1.4-final.jar org.apache.lucene.queryParser.QueryParser 'Field:(A AND -(B))' +Field:a -Field:b java -cp lucene-1.4.1/lucene-1.4.1.jar org.apache.lucene.queryParser.QueryParser 'Field:(A AND -(B))' +Field:a -Field:b So either you have a different query or something in your code is responsable for the problem.
