This method accepts a variable number of arguments. If the table has a
multi-column primary key, the number of arguments must be the same as
the number of columns in the primary key. To find multiple rows in a
table with a multi-column primary key, each argument must be an array
with the same number of elements.
The find() method always returns a Rowset object, even if only one row
was found.
