Nope. Lucene takes care of that for you.

Hi,
This is what I was talking about:
recordeddate_dt:[2008-06-16T00:00:00.000Z TO 2008
: Probably because the [NOW/DAYS-7DAYS+TO+NOW] part gets rewritten as lots
: of OR clauses. I think that you'll see that if you add &debugQuery=true
: to the URL. Make sure your recorded_date_dt is not too granular (e.g.
: if you don't need minutes, round the values to hours. If you don't nee
s, no minutes, no hours...)
