It is expected. Timestamp (with milliseconds) field will produce a lot of unique terms. Probably it will be unique for all documents. To speed-up range queries: 1-) use tdate (solr.TrieDateField) 2-) use fq=timestamp:[2010-01-01T00:00:00Z TO NOW/MINUTE+1MINUTE] Idea of 2 comes from http://search-lucene.com/m/rj7LLb20Nl1/
