This template uses Lua :
The Template:str_sub_find searches for a substring in a string at the given offset.
{{str sub find |<string1>|<string2>|<offset>}}It returns 1, if string2 is found in string1 at the given offset , otherwise it will return empty string. This makes the result easy usable in Help:Extension:ParserFunctions like {{#if:|}}.
{{#if: {{str sub find|abcdef|abc}} | Substring is found | Substring is not found }} → Substring is found
{{#if: {{str sub find|abcdef|abc|2}} | Substring is found | Substring is not found }} → Substring is not found
{{#if: {{str sub find|abcdef|def}} | Substring is found | Substring is not found }} → Substring is not found
{{#if: {{str sub find|abcdef|def|3}} | Substring is found | Substring is not found }} → Substring is found String-handling templates
