It might be worth mentioning that Timirdhi is quite low in level of authenticity among "The Authentic Six"
. He really should be able to quote a more precise reference than just the collection as a whole.
The best online collection I know is at the University of Southern California
but they only have Bukhari, Muslim, Abu-Dawud (partial), and "Malik's Muwatta" (which is not among the authentic six listed at the wikipedia article).
It's also quite likely that Mohammad said quite contradictory things throughout his lifetime and/or that the whole thing is pretty much all made up. After all, these collections were brought together a couple of centuries after Mohammad's death. It's totally implausible that it would be accurate. This is even true of the Koran itself.
