note 88522 deleted from sphinxclient.setfilterrange by danbrown

Note Submitter: nate ---- Note that while sphinx has a bigint type (64-bit unsigned int) which allows storage of negative integers, this extension does not seem to support proper filtering based on these negative integers. I'm guessing that this extension is internally taking the min/max arguments to this method and converting them to unsigned ints, which breaks everything. We've switched to using the sphinx float type instead, which seems to work fine.
