When selecting a facet, show criteria for the data descriptors shown

[agbeltran]

At the moment, when using the search box, the search criteria is shown at the top of the results page:
e.g.
'3 Data Descriptor Articles Matching primate'

Could we show the facet criteria when selecting one or more facets?

i.e. add text "Matching data repository as Dryad Digital Repository'

also for multiple facets selection:
