Microblog Search Is Not Returning Proper Amount of Results

I'm trying to track Twitter mentions on livinginhd, and have been able to for the past two weeks. But today, when I sent a query for it, it returned saying there were only four mentions and the last one was three months ago. Clearly that's incorrect. I just wanted to let you know. Is there some kind of database error going on? Other sites, including Twitter itself is logging all the recent Tweets. But I prefer using Social Mention because of all the additional features, like exporting to a .csv file.
