Final answer:
The symbol used for a 'wildcard' search on the control central search page is the asterisk (*). It acts as a placeholder for one or more characters and allows you to search for variations of a term.
Step-by-step explanation:
The symbol or key used in a search to indicate a 'wildcard' search on the control central search page is the asterisk symbol (*). When you include an asterisk (*) in a search, it acts as a placeholder for one or more characters. This allows you to search for terms that have different variations or endings.
For example, if you search for the term 'comput*', it will return results for 'computer', 'computing', 'computational', and any other word that starts with 'comput'.
Using the asterisk symbol as a wildcard in your search can help you find more results and expand your search parameters.
In a control central search, a wildcard search typically uses symbols like the asterisk (*) for multiple characters or the question mark (?) for a single character, to represent one or more missing characters in a search query.
In the context of a control central search page, a wildcard is a special symbol used in searches to represent one or more missing characters. The most commonly used wildcards are the asterisk (*) and the question mark (?). An asterisk (*) is used to substitute for any number of characters, even an empty space, allowing for a broad search. A question mark (?) replaces a single character, enabling more specific search results. For example, if you're unsure of how a word is spelled or want to include all variations of a word in your search, you might use wildcards as placeholders in your search query.
To answer the student's question directly, the question marks in the given pattern should be replaced with the appropriate wildcard symbols, depending on the level of specificity required by the search.
