FacetAPI URL processing issues

[krlucas]

Restful Search API is awesome and it works great with straightforward term facets. But I've had trouble with other type of facets, namely Date Facets: https://www.drupal.org/project/date_facets

Date Facets implements its own FacetAPI QueryType that checks FacetapiAdapter::getActiveItems() to determine how to map user configurable "terms" (like "future" or "two-weeks-ago") to date ranges.

Because FacetapiAdapter::processActiveItems() ultimately looks at the URL through FacetAPI's default URL Processor plug-in and this module uses a different query parameter and format, FacetapiAdapter::getActiveItems() is never correct.

Perhaps this module should implement its own FacetAPI URL Processor plug-in instead of parsing the URL itself and manipulating the Search API conditions directly? Alternatively, simply using the gross ?f[0]=... format instead of the much nicer ?filter[name][value]=... seems to work.
