Does statuses/filter detect all matched tweets?

[bean]

Hi,

I collected tweets by using by Streaming API(statuses/filter) like below.

r = api.post("https://stream.twitter.com/1.1/statuses/filter.json", stream=True, data={"track": "#specifiedtag"})

But, I can’t detect some tweets(about 10%) and search api can detect these tweets.

The standard streaming API provides access to up to 1% of the Twitter firehose, so if the #hashtag you are tracking is particularly popular at a point in time, you may miss some of the Tweets.
