Don't know about SkyDrive app for your Droid, but the SkyDrive app for my iphone don't seem to have any type of search.
The SkyDrive search works great on the laptop, but having a search function in a mobile app for the service manuals is kind of important to me.
Anyway I'm also now uploading the service manual collection to Google Drive. The Google Drive app has a nice search feature.
I emailed you a invite to the shared Google Drive too.
