We need to use an appropriate date format whenever we are running a query against any date field. Search queries for exact date values will require quoting or escaping because : is listed as a special character for the parser:
createddate:2001-01-11T23:45:40.60Z
createddate:"2001-01-11T23:45:40.60Z"
createddate:[2001-01-11T23:45:40.60Z TO *]
createddate:[1999-12-31T23:45:40.60Z TO 2001-01-11T00:00:00Z]
timestamp:[* TO NOW]
publisheddate:[NOW-1YEAR/DAY TO NOW/DAY+1DAY]
createddate:[2001-01-11T23:45:40.60Z TO 2001-01-11T23:45:40.60Z+1YEAR]
createddate:[2001-01-11T23:45:40.60Z/YEAR TO 2001-01-11T23:45:40.60Z]
