Have you had a look at the api? Here's an excerpt from the above uri regarding range queries. Sorting of date-fields has been subject of discussion as well: http://www.ruby-forum.com/topic/84502 Cheers, Jan RangeQuery A range query finds all documents with terms between the two query terms. This can be very useful in particular for dates. eg; 'date:[20050725 20050905]' # all dates >= 20050725 and <= 20050905 'date:[20050725 20050905}' # all dates >= 20050725 and < 20050905 'date:{20050725 20050905]' # all dates > 20050725 and <= 20050905 'date:{20050725 20050905}' # all dates > 20050725 and < 20050905 You can also do open ended queries like this; 'date:[20050725>' # all dates >= 20050725 'date:{20050725>' # all dates > 20050725 'date:<20050905]' # all dates <= 20050905 'date:<20050905}' # all dates < 20050905 Or like this; 'date: >= 20050725' 'date: > 20050725' 'date: <= 20050905' 'date: < 20050905' If you prefer the above style you could use a boolean query but like this; 'date:( >= 20050725 AND <= 20050905)' But rangequery only solution shown first will be faster
