+ <p>Similar to a SQL EXCEPT clause. Except returns records from the
first table that do not exist in the second table. Duplicate records in the
first table are returned exactly once, i.e., duplicates are removed. Both
tables must have identical schema, i.e., field names and types.</p>

"Except returns records" should be "Minus returns records" to be
consistent. I would also use "left/right" table instead of first and second
according to your example code.
