What Is Wildcar In SOSL Queries?
A wildcard is a keyboard character such as an asterisk (*) or a question mark (?) that is used to represent one or more characters when you are searching for records.
SOSL supports two wildcards:
List<List<sObject>> results = [FIND 'Univ*'....];
List<List<sObject>> results = [FIND ’Jo?n'....];
List<List<sObject>> results = [FIND 'Univ*' IN NAME FIELDS .....];
