Currently the "Did you mean?" searches all fields in the authority records. This can produce confusing results For example the term Chanties - It suggests the correct term: Shanties, but also the name of an author whose authority record mentions the title of the book: Old sea chanties. -Would it be possible to restrict the search to 4XX fields as an option?
Agreed that the Did you mean function needs some tweaking! Would it make sense to have a couple options in the 'Did you mean' display? Right now the suggestions are a bit vague/broad. The terms suggested appear to be other authorities with similar headings or where the term is found in an authority record. In addition to these 'broad' did you mean terms an improvement would be to include "See also" terms from authorities to the user. Also including the "See from" terms.
