Using Dates in REST search

I’m trying to use this query:

where='customDateProperty in (1467320400000, 1506805200000)'

It doesn’t find anything.
‘customDateProperty’ is a column, type DATETIME.

This works fine:

where='customDateProperty = 1506805200000'

What is wrong?

Hi Anton,

In our implementation the IN operator applies only to strings. To create a similar condition with dates, you could use the following:

where='customDateProperty = X OR customDateProperty = Y OR customDateProperty = Z'


Thank you Mark!
Besides, this page is missing information about the ‘OR’ operator.
