I'd like to request that when the filterToolbar posts it's data, it uses the same filter json string that the advanced search (multipleSearch:true) does (or an option is provided to do it that way).

I need to know which post params are for the search and which aren't. The way the advanced search does it, it is easy to tell.

Also, it would be nice to just have one common way of doing complex searches so we don't have to implement different functionality on the server side.

Thanks for the great work!
