After you hit search, you should either see a toast mentioning that there were no results, or you should see the searched word get highlighted in green.
Could you share a screen capture of the issue so we can investigate further? You can email it to firstname.lastname@example.org
It works, but only after I rotated the tablet to landscape orientation (the accelerometer detects which way the tablet is oriented and changes the screen to landscape or portrait). I was trying only the portrait orientation before. It never occured me to try rotating the tablet, because everything is supposed to work identically in both orientations.
So when I type the search word and press enter, if I have the tablet in the landcape orientation, it works as supposed to. But if I have the tablet in the portrait orientation when I press enter, the search doesn't work.
I'll try to let you have some info in case you want to try to fix this. The tablet is a Notion Ink Adam. The phone info screen says 'Android versoin: 2.2', 'Kernel version: 18.104.22.168-00066-g16c1dec-dirty', 'Build-number: BeastROMv2.2.1'. Let me know if you want any more info.
But it works pretty much OK for me. I'm fine with turning the tablet when I want to search.
I'll also send an email to the address you gave.
