Start a search, price range L$0 to L$0 (freebies). Get thousands of items. See that over half are demos and trials of items, which are not interesting. try to refine the search by adding the term "NOT demo" to the search box Result: 0 items. Expected Result: All items without "demo" in the name are shown The issue here appears to be that the search exclusion algorythm starts to first search on all ANDED terms in the search box, then reduces by NOT terms, and finally, by the refinements on the left (permissions, cost, etc) Search restrictions should not be reliant on searching for, say, "red shoes NOT demo", and instead just give me a full view of the possibly useful free items available on the market.
