The current Search API has a lot of rate limiting issues when used on
App Engine (User Agent just doesn't make it work) making it
unreliable. I have an app (http://www.connecttweet.com/) that a fair
amount of people (for what it is) are using in Alpha mode that I'd
like to make publicly available but I don't feel I can until searching
is more reliable...
OAuth for Search would be perfect, I am searching on a users behalf as
part of the app and already have their tokens. Can you shed any light
on when this will be possible? I'd offer to be part of an alpha or
beta on your end just to get this problem resolved.
