[SW ESB] The Rebels had X Wings on Hoth, why didn't they use at least one of those to search for Luke and Han before locking up for the night?

X-wings are starfighters, and they were no more adapted for cold atmospheric flight than the speeders were.  
An X-wing could've launched and made orbit easily enough, but hanging around for in-atmo operations is a different story.  They'd have iced up as quickly as the airspeeders and there was even less point in adapting them to operation in that environment.  
The Rebels did the right thing, they picked the right tool for the job and made it ready as quickly as they could.
