The search facilities for this site are provided by Google, who can take a while to index new pages. As I can routinly add 100+ pages per week there can be quite a back-log, meaning that you may have to do a manual search if the search box can't find it. Don't forget to use quotes ( " " ) around your search term if you get too many results.
