Do you use rounding in your dates? You can index a date rounded to the
nearest minute, N minutes, hour or day. This way a range query has to
look at such a small number of terms that you may not need to tune the
precision step. Hunt for NOW/DAY or 5DAYS in the queries.

Hi
I have a TrieDateField in my index, where I will index dates (range
2000-2020). I am only interested in the DAY granularity, that is , I dont
care about time (I'll index all based on the same Timezone).
Is there an optimun value for precisionStep that I can use so I don't index
info I will not ever use?? I have looked but have not found some info on
what values of precisionStep map to year/month/../day/hour... (not sure if
the mapping is straightforward anyway).
thanks for the help.
