I had a similar problem with date ranges. Someone on the list suggested me a solution to my problems but it was more clever than the above solution, which helps but makes the searches work slower and is memory hungry (many terms are loaded into memmory, and than searched). The solution suggested was to split dates into sub fields during indexing and use those fields while searching. This makes it more effective but harder to create a query (personally I prefer working on queries build using Lucene API, than ones parsed by QueryParser). For instance the time stamp 2004-10-01 15:34:26.001 may be split into following fields: <some-date>_year: 2004 <some-date>_month: 10 <some-date>_day: 01 <some-date>_time: 153426001 The above fields should be indexed so they can be searched. They give some nice possibilities, for instance fast and easy querying for all documents that have a date in a particular year, month or day of month. For conveniece one could also store weekdays. A query for a date range from 15th august to 10th october 2004 (in no particular query language - this just gives an idea): <some-date>_year = 2004 AND ( (<some-date>_month = 08 AND <some-date>_day >= 15) OR (<some-date>_month=09) OR (<some-date>_month = 10 AND <some-date>_day <= 10) ) As You can see it is easy to build such a query from the lucene API. The equalities are Term queries. The inequalities are Range queries. The AND and OR operators can be provided by usage of Boolean queries. Have fun implementing the solution - it has only one disadvantage. It makes results sorting not so easy. The solution for it is usage of multiple sort fields, or another stored field containing a full date (one almost surely will need to store a date for each hit, unless You want to write some baroque code to calculate date from split fields values).
