Suppress FAST headings in PAC
We'd like the ability to suppress headings in the Subject facet based on the heading's source (subfield 2 in the bibliographic record). Currently my consortium is deleting FAST and Sears subject/genre headings from the bib record because we don't want them to display in the Subject facet, and there's no way to hide them otherwise. This takes staff time, and also means the data is not available if we decide to use the headings in the future. There are probably other libraries not taking time to delete these headings, who would like a simple way to suppress them.
Idea Value
If we could simply exclude headings based on their source (e.g. $2fast), this would save the time of catalogers who currently manually delete the headings. It would also potentially benefit users in the future if a library decided to use FAST (or other) headings, because they would not have been deleted from older records.
