Paul, thanks for confirming. Can you elaborate on "the non-wildcard selection 
criteria as a leading prefix"? What does that mean?

So to handle an AND/OR statement would best be or perhaps only way to do with 
multiple views? So since Andrey wanted to support "brand and category" or 
"brand or category" he would need 3 views right?

One for item, brand and category, second for item and brand, and the third for 
item and category?
