Question

Why doesn’t WorldCat Deep-Search adapter return facet counter?

Answer

WorldCat does not return facets, but the adapter will map facet types to WorldCat fields and send the requested facet value with the “AND” Boolean operator added to the original query.
Out of the box, the adapter supports the following mappings between facets and WorldCat indexes:

    facet_topic,srw.su+all+
    facet_rtyp,srw.dt+any+
    facet_creator,srw.au+all+
    facet_jtitle,srw.ti+all+
    facet_creationdate,srw.yr+=+ (as required)

If the user selects a facet that is not mapped to a WorldCat index, no query is sent to WorldCat.

Note: Since WorldCat does not return facet counters, counters will not display for any Search Engine in a blended search with the exception of the top-level facets.
