The string-search functions in Lua script can run extremely fast, comparing millions of characters per second. For example, a search of a 40,000-character article text, for 99 separate words (passed as 99 parameters in a template), ran within one second of Lua CPU clock time.
The English Wikipedia has several templates and Lua modules which can format or manipulate strings.In this context a "string" is any piece of text forming part of a page. This help page covers a few useful techniques; look in the navbox below for the full catalogue of templa
Lua patterns are not even a subset of regular expressions, as there are also discrepancies, like Lua using the escape character % instead of \,, and additions, like Lua providing -as a non-greedy version of *. Here is a list of some of the things that Lua patterns lack compared to regular expressions:

find_character(string,char) returns integer Description Returns the position of the start of the first occurrence of the character char in string. If the character is not found most of these routines return an invalid index value – -1 where indexes are 0-based, 0 where they are 1-based – or some value to be interpreted as Boolean FALSE.
One of the bases of the Component Object Model is a common interface format, which natively uses the same types as Visual Basic for strings and arrays. D does it the same way as C++ does, with extern "C" through extern (C++) Dart includes dart:ffi [10] library to call native C code for mobile, command-line, and server applications
The text editor could replace this byte with the replacement character to produce a valid string of Unicode code points for display, so the user sees "f r". A poorly implemented text editor might write out the replacement character when the user saves the file; the data in the file will then become 0x66 0xEF 0xBF 0xBD 0x72.
Values are interpreted as strings unless tonumber (value) isn't nil, i.e. numbers should be converted to the numeric type. No effort is made to interpret tables. No effort is made to interpret tables.
