From about 2014-11-20 23:00 UTC (about 4hrs ago) we noticed that search requests with a geocode parameter are now typically returning around 10 (0-20) results when 100 were requested, and where there is well over 100 available.
Previously they would return close to the full 100 (with just the odd deleted ones removed I imagine).
This means now that if you search back in time now by paginating, you hit a zero result page rather quickly, even though there clearly are more available back ‘past’ the empty result set, and still within the week.
A very simple example that reproduces this problem is this request which searches for mentions of ‘melbourne’ within 1000km of Melbourne. Just now it only returned 11 results, but clearly there are many, many thousands of these over the last week :
/1.1/search/tweets.json?q=melbourne&geocode=-37.8143,144.963,1000km&count=100
Here is a similar query for only 10 tweets, but it only returns 1 tweet, with the results below.
/1.1/search/tweets.json?q=melbourne&geocode=-37.8143,144.963,1000km&count=10
