A Simple Search allows you to select up to five elements, a comparison operator (such as equals, not equal,) and an AND / OR condition. An example of a AND / OR condition would be "licensee = New York City AND frequency = 154.8450". For a match to occur, both search criteria must match. If either fails, both fail. An OR condition is just the opposite: only one criteria needs to match (although if both do, both results are shown. Note: Once you have used OR anything after it becomes a separate query. An example of this would be "licensee = San Gabriel AND frequency = 154.8450 OR city = Los Angeles AND state = CA". For a match to occur either the first set matches OR the second set matches. Both may match.
