Thread:Project:Support desk/Apostrophe in search results in 403 error

On my site's wiki, any search with an apostrophe in it results in a "403 Forbidden" error page. I really need to know how to fix this. Using Lucene search or Sphinx search is not an option for me, as my host does not allow either. This is a serious flaw in my Wiki that needs fixing. Can anyone offer a solution? Thanks!
