Subject Re: Indexing and searching a DateTime range
Date Mon, 09 Feb 2015 13:58:44 GMT
Hi

Long time ago,.. I used to store datetime in millisecond .

TermRangequery used to work in perfect condition....

Convert all datetime to millisecond and index the same.

On search condition again convert datetime to millisecond and use
TermRangequery.

With regards
Karthik
