It takes about a day for your text to be searchable, the recognition happens on EN servers so it has to be synced up and back.
I actually created a similar post because I did not see this one. I have followed the directions in the post above (turned on page camera and everything). One item it says to do though is turn on the flash, iPads do not have a flash so I can not do that. I am in a well-lit room with no shadows and have tried various stickers but it does not recognize them. For a $15 premium vs. a regular Moleskine, this is not acceptable.
