Boolean Searching - XOR

The last operator we will cover here is the "XOR," or the "exclusive or" operator. XOR is used to to locate records matching any of the specified terms but not all of the specified terms. For example, "dogs XOR cats" will find items with the word "dog" or the word "cat" in the record, but will not return items which have both terms in the record.

A or B, excluding A and B


The purple space represents all the records that would be returned by the search "dog xor cat."
