Why can't I get new data in my Data Model Data Set?

[chinmayc469]

I have created a root event dataset, for which constraint is index=abc.

Here whatever there is in "index=abc" are coming into this data set. But, when the index has new data, this new data is not appearing in the data set or data set pivot report.

Why won't the data set won't have real time data or new data? how do I solve this?

Thanks
