>From time to time some new Tweets would not be included in the query result, it seems like cache on the query on twitter side but it doesn't make any sense. For example right now http://search.twitter.com/search.atom?q=+nyfw+OR+%23nyfw+from%3AThisThatBeauty&rpp=20 does not include the last 2 tweets that meet the search criteria. If I change the query to http://search.twitter.com/search.atom?q=+nyfw+from%3AThisThatBeauty&rpp=20 it will include those tweets but later this query may have the same issue with newer tweets not returned. I have tried many: including/excluding the rpp param, including/ excluding the page=1 param, adding some random number at the end of the query to override local caching, etc. however nothing works.
