{{tlx|strfind short|''target''|''string''}} outputs the position in ''target'' where ''string'' first appears (e.g. an output of "3" would mean beginning at the third character in ''target''). If ''string'' is not found, it outputs zero (0). The word "short" in the title is a relic of the pre-[[WP:Lua|Lua]] implementation and has no meaning for the current version. This template is a simple wrapper around {{ml|string|find|section=#find}}, which may be used directly for more options.

== Examples ==
Use {{pf|ifexpr}} to concisely determine if this outputs zero, which lets you check if one string contains another. For example, Does "A Funny Thing Happened on the Way to the Forum (film)" contain "on the"?
