Hi, I was thinking a long time how to implement this kind of
functionality but couldn't figure out anything appropriate.
In my lucene document, I have two date fields: start and end date.
As a search input I have current date (NOW).
I need to display all documents for which current date is between
start and end dates.
I know that this could be performed by two RangeQuery-es, ie.
startDate:{19700101 to NOW} AND endDate:{NOW to 29990101}
but since the index could be very large, performance would not be
very good.
RangeFilter is not a good idea as well, since I would have to filter
on two fields (or maybe it would with ChainedFilter?).
Does anyone know which approach would be the best in this kind of
situation, performance wise?
In Lucene 2.9, there is much better performance for range queries on
numerics, you might try that.
