: I was wondering what would be the best FieldType for storing date with a : millisecond precision that would allow me to sort and run range queries : against this field. We would like to achieve the best query performance, : minimal heap - fieldcache - requirements, good indexing throughput and : minimal index size in that order.
if you don't need sortMissingLast or sortMissingFirst then TrieDateField should be exactly what you are looking for. : We could probably use TrieLongField, however, as we understand, this : doubles the heap requirements for fieldcache. Was wondering if there is : a clever way of achieving this without adding to the heap. TrieDateField uses the long[] FieldCache, I'm not sure what you mean by "doubles the heap requirements" ... unless you are comparing to "int" ? In that case: using TrieIntField seems like what you want? (but if you are comparing to DateField, the FieldCache for TrieDateField is going to be a lot smaller) -Hoss -- http://lucenerevolution.org/ ... October 7-8, Boston http://bit.ly/stump-hoss ...
