I want to use group by aggregate function with a field called "field1". Some events in my data donot consists of this field. (i.e field1 = null). Now when i try to use group by with this field the events where field1=null are skipped and not shown in our output.
How to use the group by function with fields where the coverage of the field is not 100%?

tstats works on the accelerated data model, right? Then you probably need to adjust your acceleration searches to ensure those fields are never null. So basically include the fillnull in the acceleration search and rebuild the data model.
