I use mine for geocaching and have tried a couple of different methods to get cache info onto my 770. One way is to run your pocket query with the "also send as ebook" checked. I simply upload this file into the unit and use FBReader to read it.

But the other way i've found to do it is the way i like better. Download your query into GSAk, then export it to html. Upload this file into the unit then simply open it, then find and click on index. The file then opens into the built in browser.
