Does Lucene support negative phrase queries like -"hello dolly" ? Or do I need to subtract from some other term like: joy -"hello dolly" ? My intention is to find all documents that do not have the words "hello" and "dolly" adjacent to each other. 2. And also, does "hello dolly" mean the same thing as the proximity query "hello dolly"~1 ? Thanks!
