If the SearchList contains only one value, it acts exactly like PatternCount, except that CaseSensitive option.

The order of the value list doesn't matter. For example, if Text is "888 888", and the SearchList is "888¶8". The search of "888" always returns 2, the search of "8" always returns 6, no matter the order of the list.

I use this function to check invalid characters in a string.

The reason I use Substitute instead of direct PatternCount is for the CaseSensitive. PatternCount don't have this option so I had to do it this way.

With this function the validating multiple invalid characters became easy. Here is and example:

Not PatternCountMultiTotal ( Self ; "|¶'¶\"¶,¶;¶ ¶/¶\\" ; 0 )

The above will validate against the characters | ' " , ; / \ and space. You can add any characters or words that you don't like.

Also a good use of it is to search multiple derogatory terms. You can have a long list of words that's not allow, run this function and you will see any hits.
