Solution
Answer
In Search Processing Language (SPL), the special character that is a wildcard used to substitute with any other character is the asterisk *.
Wildcards are important in search queries because they allow for a more flexible search, accommodating variations of terms. The asterisk * can replace any set of characters, making it possible to find results that might differ slightly in spelling or structure. For instance, if you search for test*, the results will include entries like test, testing, tester, and testimony.
The other options given in the question, such as !=, |, and =, serve different functions within SPL. The != operator is used for "not equal", | is used for piping commands, and = is typically used for comparisons or assignments. Therefore, the correct answer is the asterisk *.
