Hi,
those are probably accounts which twitter filtered out. The docs are pretty
clear on this and give practical advice:

> Both the Streaming API and the Search API filter statuses created by a small

> samples and keyword track, are filtered by this status quality metric.
> Results that are selected by user id, currently only results from the follow
