%x, %X : Scan an integer as an unsigned hexadecimal number. %o : Scan an integer as an octal number. %s : Scan a character string. The scan terminates at whitespace. A null character is stored at the end of the string, which means that the buffer supplied must be at least one character longer than the specified input length.
The string-search functions in Lua script can run extremely fast, comparing millions of characters per second. ... Although Lua has been used to scan entire articles ...
contains(string,substring) returns boolean Description Returns whether string contains substring as a substring. This is equivalent to using Find and then detecting that it does not result in the failure condition listed in the third column of the Find section.

Video of the process of scanning and real-time optical character recognition (OCR) with a portable scanner.

For example, in the text string: The quick brown fox jumps over the lazy dog. the string is not implicitly segmented on spaces, as a natural language speaker would do.

iOS 15.4 brought a new level to scanning on iPhones and iPads when it introduced the scan text feature. With this tool, you can scan your written grocery list or to-dos into your phone’s notes app.

A string-searching algorithm, sometimes called string-matching algorithm, is an algorithm that searches a body of text for portions that match by pattern. A basic example of string searching is when the pattern and the searched text are arrays of elements of an alphabet ( finite set ) Σ.
