When creating a bar chart with only one "term" aggregation, the results show real amount of items (assuming simple count metric on the Y-Axis). However, when adding sub-aggregation of a "term" type, total count reduces.
Well, I understand the reason. I had to pick top X entries on the sub-aggregation, and certainly I filtered out some portion of my data.
It would be nice to have my top X entries, and additionally artificial term named "Others", which shows cumulative aggregation for the rest of my data.
Please let me know if anyone else has similar problem and whether or not you believe this is a legitimate request.
