I think we'll want something more granular here.  Just looking briefly over the mockups we have titles like:

* Within this list
* Within databases
* Within this collection
* Limit your search

Given that the wording isn't exactly 1:1 with the access point naming (e.g. `this list` vs `course_reserve`) we may want to use the access_point as an i18n key so we can choose the wording for each access point individually.

    search:
      facets:
        access_point:
          databases:
            title: "Within databases"


Also, I'm not sure if you can pass a default/fallback for a particular i18n key but if so we could do away with the `if page_location.access_point?` conditional in the `FacetsHelper`.
