* First positional parameter or |text is the text to be searched for.
* Optional parameter |title is the page title, defaults to the current page.
* Optional parameter |plain is either true for a plain search (default), or false for a [[mw:Extension:Scribunto/Lua reference manual #Patterns|Lua pattern]] search.
* Optional parameter |nomatch is the value returned when no match is found; default is nothing.

A startswith function similar to {{ml|string|endswith}}. Both parameters are required, although they can be blank. Leading and trailing whitespace ''is'' counted, use named parameters to avoid this if required. Outputs "yes" for true and blank for false so may be passed directly to #if.

===isnumeric===
Implements {{tl|isnumeric}}, which tests whether a value is numeric (or at least, that it can be treated as such by the [[:mw:Extension:Scribunto/Lua_reference_manual#Language_library|Scribunto language library]]). By default, it will pass through the parameter if it's numeric and be blank if it's not. If the parameter <code>boolean=true</code> is given, then it will output <code>1</code> if numeric and <code>0</code> if not numeric.
