Count limit

Hi people,

I have doubt about the count limit of queries on update firehose table. Say, I've typed this query on my console:
"select source, suid, type from social.updates.search(1100,100) |sort(field="pubDate");"

But I got no update json object, and I've noted this point, at tree output, inside the console:

http-status-code : 400
http-status-message : Bad Request
content : http://social.yahooapis.com/yosapt_mt_feed...00&hits=100

So, anybody could answer me what these things mean? Can I get more than 1100 updates json objects?

Cheers and hugs,
Saulo
