You don't want to strain it in the sense you'd be using a strainer or in any way chancing oxidizing the beer, but you could try a sanitized hops bag over the end of the racking cane to try to avoid sucking up debris.
I've never had any luck at all doing that (darn bag caused clogging), but I'm pretty proficient with racking since I'm an old winemaker and usually you can avoid the debris with careful racking. If you start the siphon in the middle of the beer, and lower it as the level of the beer lowers, you can usually avoid sucking up chunks. Also, as was mentioned, cold crashing will help alot with getting the suspended debris to fall.
