String

default value: {1,1} - requires matching minimum 1 and maximum 1 times

charset = character set name enclosed in single or double quotes (for example charset="ISO-8859-1")

locale = string specifying IETF BCP 47 language tag enclosed in single or double quotes (see the list here). The default locale is English.

Note

In case the constant contains a single quote or double quote you may either use the other for enclosing (i.e: use double quotes for enclosing if the string contains a single quote or vice versa).

Alternatively, you can escape it with a preceding backslash character \ (0x5c ASCII).

Constants are usually less interest for analytical purposes, hence in most cases, they are just matched - i.e values not exported for the query.

Example

Matching one or more characters 'a'.
