Short and Sweet -
Before you start inquire with QleeQ, you can and sometimes should check if the phrase you are interested in is in QleeQ's Wisdom (Qdb).
To do that, before you type you're Sensetence - you should type your Subject phrase.
If you get a Real or Green result, go ahead - we are deep into providing you answers about it.
