If that were possible, I suspect you'd hit something like 75% of the
items (because when the reference string contains a single word, it is
iterated over all the words in the message - otherwise you'd get no hit).
Phonetic searches are only meaningful when done on small amounts of data.
An entire mail message does not sound like anything at all, there are
just too many words. Furthermore it contains so many words that the
probability that any of the words sounds like a one-word reference string
is pretty high. This is pretty much like searching very short sequences
of letters in the mail body.
