This template wraps the function {{#invoke:String |find|...}}, and provides the extra option to return an alternative string (including a blank string) when nothing is 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, 0 is returned.
Set |nomatch=anytext to replace that 0. Also, |nomatch= <blank> returns blank not 0. Note: outer spaces are not conserved.
Using the nomatch option
