Index items typically have a last modified date associated with them. Queries can be constrained to items with a certain date or a range of dates. The XML representation of this constraint is:
<date op="num_op">date_string</date>
This constraint has the same comparative operator values as the number property constraint (see Property Constraints). The date_string is either a valid date value or a range of valid values, expressed as initialdate-finaldate. The valid forms of data values are:
YYYY – A four digit year
YY – A two digit year, assumes 1900.
MMYY – Month number followed by two digit year
MMYYYY – Month number followed by four digit year
MMDDYY – Month number followed by day number followed by two digit year
MMDDYYYY – Month number followed by day number followed by four digit year
monthDDYY – Month name followed by day number followed by two digit year
monthDDYYYY – Month name followed by day number followed by four digit year
For all forms, the month, day, and year components must be separated by one of the following delimiters: space, hyphen, period, comma, slash or back-slash.
