can someone help me with this please:
s_test = "this is a test string this is a test string " function String.Wholefind(Search_string, Word) _, F_result = string.gsub(Search_string, '%f[%a]'..Word..'%f[%A]',"") return F_result end A_test = String.Wholefind(s_test,"string") output: A_test = 2
So the frontier pattern finds the whole word no problem and gsub counts the whole words no problem but what if the search string has numbers?
s_test = " 123test 123test 123" B_test = String.Wholefind(s_test,"123test") output: B_test = 0
seems to work with if the numbers aren't at the start or end of the search string

Your pattern doesn't match because you are trying to do the impossible.
After including your variable value, the pattern looks like this:
%f[%a]123test%f[%A]. Lo que significa:
- %f[%a] - find a transition from a non letter to a letter
- 123 - find 123 at the position after transition from a non letter to a letter. This itself is a logical impossibility as you can't match a transition to a letter when a non-letter follows it.
Your pattern (as written) will not work for any word that starts or ends with a non-letter.
If you need to search for fragments that include letters and numbers, then your pattern needs to be changed to something like
