approximately 238,000 pages
.
To avoid major disruption and server load, any changes should be tested in the template's
/sandbox

subpages, or in your own
user subpage
. The tested changes can be added to this page in a single edit. Consider discussing changes on the
talk page
before implementing them.

 | This template uses
Lua
:
|
{{
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-
Lua
implementation and has no meaning for the current version. This template is a simple wrapper around {{
#invoke:string
|find}}, which may be used directly for more options.
Examples
Use {{
#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"?
