Hi John, I am not sure about the way Solr implements range query. But it looks like, that Solr is using org.apache.lucene.search.ConstantScoreRangeQuery which itself is using org.apache.lucene.search.RangeFilter
So Solr do not rewrite the query to a large Boolean SHOULD, but it is reading all terms for the "range"-Field. This could be slow. If the RangeFilter is used many time a CachingWrapperFilter would speed up the search. You also could (try to) read the terms from memory instead of hard disk. Because a timestamp is only a long = 64bit, a appropriate solution would also to store the timestamps in main memory for a fast RangeFilter implementation.
