Re: [twitter-dev] Re: Search API rate limit change?
I just wanted to add to this. The 420s have let up for the most part and I'm no longer seeing rate limiting behavior significantly different from the norm. I've noticed that many result pages are coming back with empty results but if I re-request the same page (after a couple second delay), I can often get results for that page. These are for queries with very low tweet velocity, so it's not like these are new results coming in. Is this related to http://status.twitter.com/post/3785043723/slow-searches ? Thanks.

For some of you it sounds like your code that handles rate limiting didn't react appropriately.

Put another way it isn't a good idea to make requests to the API at the velocity that caused the 420 response before. As always, the rate limits are there to ensure the system is responsive and available to as many users as possible.
