I would need an entirely different interface to support letting a user query the database (and then lots of code to figure out how to process the returned result because I can't be sure what the user actually queried). That would also probably result in tons of questions from users about the structure of the database (eating up support and development time), and some users might get adventurous and mess up the database if I allow any query to be executed. I'd rather just have a limited set of filters that I can control so that I know how to properly process the results in my framework.
