function facetapi_apachesolr_date_range in Facet API 6

Gets the range of dates we are using.

@todo integrate this into facetapi_apachesolr_facetapi_date_range_prepare() once we have a "range limit callback".

Parameters

$query: A Solr_Base_Query object.

$facet_field: A string containing the name of the facet field.

Return value

An array containing the gap and range information.
