# elements of a number of searches.  My "solution" (heh heh heh) is to
# store all data in a hashref, indexed into the instance as DATA; if
# the user is tieing an array or scalar (Tie::Google treats them
# identically), then we store the results in the key named $KEY, so
# that we can treat all types of ties consistently; otherwise, search
# results are keyed by query.
