I think you are missunderstanding what date faceting does. you have a
facet.date.gap of +1DAY, which means the facet count is anything between
2009-10-23T18:30:01Z and 2009-10-24T18:30:01Z inclusively. you can verify
this using a range query (not a term query) ...
daysForFilter:[2009-10-23T18:30:01Z TO 2009-10-23T18:30:01Z+1DAY]
if you only want to facet on a unique moment in time (not a range) then
you cna use facet.query ... or you can set the facet gap smaller.
you should also take a look at facet.date.hardend...

Thanks Hoss, the problem is resolved.
The real problem was my query parameter. I was storing daysForFilter with
offset of 1 sec, and date in query parameter "facet.date.start" also had
same offset. This was causing the overlaps, as in the facet value of
2009-10-23T18:30:01 was matching both 2009-10-23T18:30:01 and
2009-10-24T18:30:01.
just changing the query to
"q=<something>&facet=true&facet.date=daysForFilter&facet.date.start=2009-10-23T18:30:00Z&facet.date.gap=%2B1DAY&facet.date.end=2009-10-28T18:30:00Z"
works.
thanks any way.
regards,
aakash.
