These two queries should give the same result. Could you provide a test case that reproduces this? A simple example test case is in the source code of TestNot.java currently available from here: http://svn.apache.org/repos/asf/lucene/java/tags/lucene_1_4_3/src/test/org/apache/lucene/search/ You could also add a main() method when you don't want to use JUnit. > > Another combinations of MUST and SHOULD. > > "T:files T:deleting +C:production +C:optimize" hits 1 document. > "(T:files T:deleting) (+C:production +C:optimize)" hits 1 document. > > Isn't it weird? Is it an expected behavior? That depends on the index that is being searched. A correct result could be the same document for both queries.
