here you can simply go for field:[20020101 TO ] and leave the end
blank. If you want to do fast numeric searches you should use
NumericRangeQuery instead.

so what you do here is basically requesting as many documents as you
need lets say 100, then you display it. Once you need the next hundred
you search again requesting 200 results and once the search returns
simply discard the first 100
use this as the basic method if you simply use a query without filters
or anything.

 public TopDocs search(Query query, int n)

method states only to call that method if you need ALL the results.  I definitely don't need
all but need to page through the

I want a reference held into the indexed tree so it can keep giving me the next 100 results.

in lucene you must search again to the the next 100 but in general the
search should be very fast.

lemme know if you have more quesitons.
