Wrapper for findpagetext function in Module:String2.

The Findpagetext template returns the position of a piece of text in the wikitext source of a page. It takes up to four parameters:

  • 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 Lua pattern search.
  • Optional parameter |nomatch is the value returned when no match is found; default is nothing.
Examples
{{findpagetext |Youghiogheny}} → 761
{{findpagetext |text=Youghiogheny}} → 761
{{findpagetext |text=Youghiogheny |nomatch=0}} → 761
{{findpagetext |text=Youghiogheny |title=Boston Bridge |nomatch=not found}} → Lỗi Lua: bad argument #1 to 'find' (string expected, got nil).
{{findpagetext |text=river |title=Boston Bridge}} → Lỗi Lua: bad argument #1 to 'find' (string expected, got nil).
{{findpagetext |text=river |title=Boston Bridge |nomatch=not found}} → Lỗi Lua: bad argument #1 to 'find' (string expected, got nil).
{{findpagetext |text=[Rr]iver |title=Boston Bridge |plain=false |nomatch=not found}} → Lỗi Lua: bad argument #1 to 'find' (string expected, got nil).
{{findpagetext |text=%[%[ |title=Boston Bridge |plain=f}} → Lỗi Lua: bad argument #1 to 'find' (string expected, got nil).
{{findpagetext |text=%{%{[Cc]oord |title=Boston Bridge |plain=f}} → Lỗi Lua: bad argument #1 to 'find' (string expected, got nil).

The search is case-sensitive, so Lua pattern matching is needed to find river or River. The last example finds {{coord or {{Coord. The penultimate example finds a wiki-link.
