xPFilter (Fn2search;Fnsearch)

The master function calls the appropriate sub function depending on how many words are input - hence there are 4 sub functions below - just to avoid doing more processing than necessary. This is called in the portal filter.
Although it is much slower than a scripted find it enables users to find records they otherwise miss with a normal string search - it is very popular with users.
I published a 3 word version on the FM Community site.

The input is the fieldname to search and name of the global field used for search in the Ui. The fieldname to search in this system is the autoentered summary field containing all the data on which we want to search.
