Hi all,

But this is not what I am looking for:

https://www.zoho.com/creator/help/script/built-in-functions/built-in-function-string-equalsignorecase.html

I would like get the return of strings which are equal

Example1:
StringA: Project Management Software
StringB: Project Management Application

matchResult = matchIgnoreCase.(StringA, StringB);
return matchResult;
// Return "Project Management"

Example2:
StringA: Studying Project Management
StringB: Project Management Application

matchResult = matchIgnoreCase.(StringA, StringB);
return matchResult;
// Return "Project Management"

Thank you in advance.
