Reading in real time all tweets with a given hashtag

[stecnalia]

Given a certain hashtag e.g. #quiz1, I want to create an application that reads in real-time all the tweets that are posted containg this hashtag. Does the Streaming API guarantee that no tweets with the hashtag will be lost? If not, is there a way (free or not) to guarantee that no tweets are lost?
Thanks in advance, Sonia

If the result of your hashtag filter on the Streaming API is < 1% of all tweets at that time, then you should receive all of the tweets with that hashtag at the time your app is running. If the result is more than 1%, then you will miss some. To avoid that, we’d point you at something like the Gnip PowerTrack API.
