Usage
{{Str find|text|sub_string}}
Returns the position of first appearance of sub_string in text.
- The comparison is case sensitive.
- Returns -1 if sub_string not found
- Character position is 1 based (not 0 based as usual in calculations).
- If sub_string is empty, this routine returns 1. This case will often have to be handled specially.
