The lowest 10 percent earned less than $13. The way I understand accelerated data model summaries is that they are basically independent traditional databases with a rigid schema: they just contain the values for the fields you specified in the definition of the data model. this technique can be seen in so many malware like trickbot that used MS office as its weapon or attack vector to initially infect the machines. user This works perfectly, but the _time is automatically bucketed as per the earliest/latest settings. With classic search I would do this: index=* mysearch=* | fillnull value="null. List of fields required to use this analytic. Use the datamodel command to return the JSON for all or a specified data model and its datasets.
