Use a layering method for filtering on TRAC to enable clients to combine filters using the already existing operators (AND, OR -() etc.). E.g. to look at more than one competitor or topic within a search and also in isolation without having to type out new filters every time you want to look at this. This is something that Brandwatch apparently does very well and was highly requested by our client Visit Scotland, and would greatly decrease the amount of filters they'd have to create.
