You can—and should—add additional search terms when using insource:/regex/ to reduce the amount of text being processed. For example: For example: polish insource:/polish/ finds pages that match a case-insensitive stemmed keyword search for "polish" (including "polished" or "polishing"); then does a case-sensitive regex search within those ...

However, it can make a regular expression much more concise—eliminating a single complement operator can cause a double exponential blow-up of its length. [26] [27] [28] Regular expressions in this sense can express the regular languages, exactly the class of languages accepted by deterministic finite automata. There is, however, a ...
Whitespace cannot easily be avoided when a page with little text, often a stub, contains an infobox or similar vertical template that is quite tall along with a navbox or similar horizontal template at the bottom, and the amount of text on the page takes up far less space than the template to the left. Even without a horizontal template, there ...
Regular expressions (or regex) are a common and very versatile programming technique for manipulating strings. On Wikipedia you can use a limited version of regex called a Lua pattern to select and modify bits of text from a string. The pattern is a piece of code describing what you are looking for in the string.
Greed, in regular expression context, describes the number of characters which will be matched (often also stated as "consumed") by a variable length portion of a regular expression – a token or group followed by a quantifier, which specifies a number (or range of numbers) of tokens. If the portion of the regular expression is "greedy", it ...

It includes spaces, tabs, and new line formatting controls. In Unicode, such a character has the property set WSpace=yes. In version 16.0, there are 25 whitespace characters.
