Hi at all,
I have a search very simple (`tag=MYTAG`) that gives to me results that I use in a timechart count by a field (my_field) and correctly runs giving time distribution for the two values of my_field (OK, KO).
tag=MYTAG | timechart count by my_field
If I use it in a Data Model, I have as result of the related Pivot three values (OK, KO, NULL) instead the correct two values.
Exploding results as search, I see that Data Model added to my search (`tag=MYTAG`) the additional condition
`(index=* OR index=_*)` that gives the problem of the NULL values.
Why this appens? I was wrong in Data Model Configuration?
Is there a way to avoid this?
Thank you in advance.
Bye.
Giuseppe
