The wildcard operator is one of the most powerful Boolean operators in your toolkit. At Fastcase, we use the asterisk symbol (*) as our wildcard.
When you put the asterisk after the stem of a word, your search will return documents containing any word beginning with that stem.
Termin* → Search results containing the words termination, terminated, terminal, etc.
Litig* → Search results containing the words litigator, litigation, litigious, etc.
Eat* → Search results containing the words eat, eaten, eatery, eaters, eating
As you can see, using the wildcard operator is a very powerful and flexible tool. Think about incorporating the wildcard regularly in your searches.
