Wildcard Characters for Search

The "^" activator also precedes special characters defined as wildcards. A wildcard character is used to replace a group of characters, such as a group of letters, numbers, punctuation marks, etc., or a special element of the text.

The wildcard characters that can be used are as follows:

- "*" (asterisk): any character except space.

- "?" (question mark): any letter of the alphabet.

- "%" (percent sign): any consonant.

- "&" (ampersand): any vowel.

- "@" (at sign): any accented vowel.

- "<" (less than): any lowercase letter.

- ">" (greater than): any uppercase letter.

- "#" (hashtag): any number.

- "_" (underscore): any punctuation mark.

- "!" (exclamation mark): any other character except letters, numbers, or punctuation marks.

- "p": end of paragraph.

- "l": end of line.

- "t": tab character.

For example, if you enter the string "terr^&," the words "terra," "terre," etc., will be found in the document.

To use wildcard characters, it is necessary to activate the corresponding search criterion from the appropriate options list.
