what's the text function to get the number of of character set appearences in a text?
I believe you want to look into substringcount:
substringcount( text , substring)
Returns the number of times the string substring appears within the string text. The result is an integer. If there is no match, 0 is returned
substringcount ( 'abcdefgcdxyz', 'cd' ) returns 2
Thank you, Stephan.
