I have been told by a development partner that we cannot use the normal Twitter search widget - found here - https://twitter.com/about/resources/widgets/widget_search because of the API rate limit. My understanding is that the rate limit applies to the API as used by app developers, and not to the official widgets. Who is correct?
This page - http://dev.twitter.com/pages/rate-limiting - has information on this (important stuff highlighted in bold below)
The API limit is linked to an IP address but does allow 150 requests per hour.
OAuth calls are permitted 350 requests per hour.
Hope this helps
