I see the option of filtering...but, not the most efficient process, also needs to be able to search completed tasks...if this can't be done, I can submit as feature request.
Indeed, the only way to search on the Android app is currently the Filter option, but we will consider improving it or add a regular search box. You're welcome to vote for this request: http://todoist.com/Vote_Android/showProposal/25/
As for completed tasks - we will address this in the future as well. You can add a request for it to the Votebox.
Thank you for the quick response. Love the product.
