Regular expressions are used in search engines, in search and replace dialogs of word processors and text editors, in text processing utilities such as sed and AWK, and in lexical analysis. Regular expressions are supported in many programming languages. Library implementations are often called an "engine", [4] [5] and many of these are ...
A regex search scans the text of each page on Wikipedia in real time, character by character, to find pages that match a specific sequence or pattern of characters. Unlike keyword searching, regex searching is by default case-sensitive, does not ignore punctuation, and operates directly on the page source (MediaWiki markup) rather than on the ...

In many programming languages, a particular syntax of strings is used to represent regular expressions, which are patterns describing string characters. However, it is possible to perform some string pattern matching within the same framework that has been discussed throughout this article.
His 302 regular season wins, leading the Patriots and the Cleveland Browns, is No. 3 on the all-time list, trailing only George Halas' 318 and Don Shula's 328.
In computer science, an algorithm for matching wildcards (also known as globbing) is useful in comparing text strings that may contain wildcard syntax. [1] Common uses of these algorithms include command-line interfaces, e.g. the Bourne shell [2] or Microsoft Windows command-line [3] or text editor or file manager, as well as the interfaces for some search engines [4] and databases.

A Japanese sake maker is going where no sake maker has gone before: space. Asahi Shuzo, the company behind popular Japanese sake brand Dassai, plans to blast sake ingredients to the International ...
Add solar superflares to the list of natural disasters of concern. Superflares are extremely strong solar flares – explosions with energies up to ten thousand times that of typical solar flares.
