Created attachment 3577 [details] [review] Escape the double quotes in authority search queries to prevent errors. Searching for any term containing double-quotes returns an error 500 when doing an authority search on this page : authorities/authorities-home.pl . The error is returned because the double-quotes aren't escaped when creating the pqf search query, which breaks the query. Patch attached which does some escaping on double-quotes when constructing the pqf query.
It works as expected, signed off.
Pushed please test
