Incorrect result counts after AquaBrowser facet drill down

[ucamhal]

When drilling down into aquabrowser search results, the result counts after drilling are often not the same as the advertised count on the facet.

For example:

1. search for "Darwin":
   • Lib Gateway 7322 results
   • AquaBrowser 7322 results
2. The "Subject" facet value "Evolution" has 572 results for both. Lib Gateway & Aqua. Drill down into the "Evolution" facet:
   • Lib Gateway 1763 results (more than expected)
   • AquaBrowser 572 results (as expected)

The query performed by Library Gateway for this drill down into Evolution is:

• http://search.lib.cam.ac.uk/result.ashx?cmd=find&noext=false&output=xml&q=Darwin%20subject%3A%22Evolution%22&searchmode=assoc
• e.g., the query is: Darwin subject:"Evolution"

Whereas on AquaBrowser the query remains as Darwin but the ref query param contains the value 22984 which is the ID of the "Evolution" "Subject" facet. Subsequent drill downs are appended to the ref value, separated with semicolons.

It appears that Library Gateway is not applying selected facets in the correct way. Or at least not in the same way that AquaBrowser does.
