For my project, I've found that I'm able to pass additional arguments to a faceted search view display by adding a querystring to the end of my faceted search url. For example:

http://localhost/search/results/field_manufacturer%3A380%20taxonomy%3A32?kw=1000

Now I'm trying to figure out how to add that querystring to the guided search facets (and facet removers).

I'm about to get under the hood to see how that can be done, but perhaps one of you wizards out there could point me in the right direction?

I'll report back if I figure it out...

Thanks in advance,
Mike
