ranged query didn't work, got exception...
"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."
I tried that and got an exception...
I need to do something like String queryStr = "author:dean and date:[" + date1 + " TO ]"; so can I do a combination of NumericRangeQuery and text query and is there any example on this?

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.

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.

Sweeeet, * worked, but SHUCKS.....query completely returns no results. I don't get it...it gets into the lucene code and since there is no "Scorer" returned, it seems to skip over any results that would be valid :(....any ideas what is wrong with this program....

I think you need
field:[20020101 TO *]
although the "*" option isn't available in some versions (pre 3.1?) and
you just have to supply a big value:
field:[20020101 TO 99999999]

I think you need
field:[20020101 TO *]
although the "*" option isn't available in some versions (pre 3.1?) and
you just have to supply a big value:
field:[20020101 TO 99999999]
