This template implements the :Module:String|find function ({{#invoke:String|find|...}}).
It has an extra option to return any text or <blank;> when not found.

{{In string|source_string|target_string|start_index|plain_flag|nomatch_returntext}}- or
{{In string|source=source_string |target=target_string |start=start_index |plain=plain_flag |nomatch=nomatch_returntext}}
{{In_string
|source=
|target=
|start=
|plain=
|nomatch=
}}
- By default, when the target is not found,
0is returned. - Set
|nomatch=anytextto replace that0. Also,|nomatch=<blank> returns blank not 0.
- Note: outer spaces are not conserved.
- Using the nomatch option
