What I am trying to do? I need to query documents by comparing month and day with given params. eg., if the params are {day: 20, month: 02}, and (Greater than) I need to retrieve all docs which has month > 2 or (month == 2 and day > 20).

Your script needs to access the field like this:

doc['custom_data.date1'].date.getMonthOfYear()
