Hi TJ. If you use a circle query shape, it's O(N), plus it puts all the points in memory. If you use a rectangle via bbox then I'm not sure but its fast enough that I wouldn't worry about it. If my understanding is correct on Lucene TrieRange fields, it's O(Log(N)). If you want fast filtering no matter what the query shape is, then I suggest Solr 4.0 SpatialRecursivePrefixTreeFieldType ("location_rpt" in the example schema)
