此模板使用Lua语言：

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.

Usage

{{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.
