Matching Simple Strings

The simplest and most common type of regex is an alphanumeric string that matches itself, called a "literal text match". A literal text regex matches anywhere along a string. For example, a literal string matches itself when placed alone, and at the beginning, middle, or end of a larger string. Literal text matches are case sensitive.

Using regexes to search for simple strings.

Example 1: Search for the string "at".

Example 2: Search for the string "email".

Example 3: Search for the string "abcdE567".

Note: Regular expressions are case sensitive unless case is deliberately modified.
