const person = { dob: xs.date("1979-02-03") };

person.dob < thrirtyYearsAgo; // trueYou can do date math with xs.duration types. In the above case, I'm subtracting 30 years from the current date. xs.date.prototype.subtract() returns an xs.date. You can compare that xs.date to any other xs.date. To do this comparison in MarkLogic's indexes you'll need to create a range index <https://docs.marklogic.com/guide/concepts/indexing#id_51573>. A range index, as its name implies, queries efficiently for ranges of typed values, for example, dates less than thirty ago from today. cts.rangeQuery(cts.jsonPropertyReference('dob'), '<', thrirtyYearsAgo); // requires a range index of type xs:date on the dob JSON property Justin > On May 22, 2017, at 1:08 PM, Shiv Shankar <shiv.shivshan...@gmail.com> wrote: > > Hi, > There is a dob json property in the documents and I need to search on dob > based on age wise i.e age > 30, age >30 and age <50.
