Search/tweets, count field is different from actual result



Hi, I’m having problems with the search/tweet method.
First time I use it everything works fine, but the second time the response is like this

“statuses”: [],
“search_metadata”: {
“completed_in”: 0.008,
“max_id”: 658872058068226048,
“max_id_str”: “658872058068226048”,
“query”: “%23Uruguay”,
“refresh_url”: “?since_id=658872058068226048&q=%23Uruguay&lang=en&include_entities=1”,
“count”: 100,
“since_id”: 658871894473502720,
“since_id_str”: “658871894473502720”

Statuses are empty but the metadata clearly shows that there are 100 results
Is anyone having the same problem?
It happens if I try with the OAuth Tool also
