           Summary: Refine search displays 4xx fields from authority

When looking at the results from a search, the Refine Search column displays
the headings from the 1xx and 4xx fields in the authorities.
This means that all the variations on a term that are not used in the catalog
appear as search options.  (For example the half dozen different ways to spell
and punctuate Ralph Vaughan Williams).
This should not be happening. It is confusing to the patrons and needlessly
extends the list of search terms (as all the 4xx terms point back to the
correct 1xx)

Heather Hernandez commented:
"if you click one of the facets from a 400 field, it does return correct
results based on the 100 field--e.g., if you do a search on Sea Poetry:
http://keys.bywatersolutions.com/cgi-bin/koha/opac-search.pl?q=sea+poetry

And you click on the facet "Sinbad," (a 400 in the aut record) it will
return the two results by "Dingle, Aylward Edward," (which is the 100 field
in that aut record), but the user will have no idea why--there's no
evidence that your search has been redirected due to your selecting a "see
from" reference."

records But are continuing to work on it.
It is something to do with the IncludeSeeFromInSearches systempreference
If you have had this on, or have it on, it makes the links so that when you
search for
the 400, you can still find results.

To do this its linked, however in 3.12.x and 3.14.x it appears these links were
filtered
out when building the facets and for some reason this is not occuring.

I think its to do with an indicator of z that gets added to 100 (of the biblio)
on indexing (you wont see
it on the record itself, its added when indexing)

The old code got rid of this, so no, this is not required behaviour".
