While we are also developing a query-building UI, users must be able to enter text queries as well. What do other folks do? I mean, this is pretty bad. I can hardly go back to my scientists and tell them Lucene is unable to handle 2 boolean operators, that they should parenthesize everything by hand. I mean, that's just cheesy.
What I'm doing for our application is to advise users to put in the parentheses. It's cheesy, but safe.
What I would do if the application were relatively new is to advise against using AND/OR/NOT, and using + and - instead since it seems that syntax is relatively reliable. Actually I would probably consider removing the AND/OR/NOT syntax from the query parser itself.
