Count also occurences that are not present for alerting

[sbsbb]

I've made some searchs for alerting, but my problem is when I make a | stats count, if some occurences are not present in the time frame I search, the count will no be 0, they won't be anything, how can I change this...

For exemple at the moment if messege 1 not present, I have this
Count
Messege 1 5
Messege 1 5

I would like this

          Count

Messege 1 5
Messege 1 5
Messege 0 5

I'm not sure, but it seems this doesn't work if there is no event at all...

for exemple, if I'm counting the error by partner,
if I've got over the search time range 0 messages from that parner, there is no line for it in the results...

An fillnull doesn't help... or am I wrong ?
