Well, the fine print is ambiguous at best.  But reading between the lines,
my guess is that it a search for "foo" is a search for an entry containing a
word that BEGINS with "foo".  Thus it would find  "foo" and "foo." and
"foobar." but not ".foo" --- which is probably pretty good for most real
applications you'd want to write.
