…led test failure This test indexes 150 documents. In case the test index has a high number of shards, it can happen that no documents get sampled. I think this is expected behaviour in this case. This commit adds a special case for this situation, by expected other counts to be 0 if sampled doc count is 0 as well. Closes elastic#89818

LGTM. I do wonder if we should return an error, or at least a warning, if the sampler ever gets zero docs. @benwtrent is on parental leave right now, but might be worth discussing with him when he gets back.

Salvatore and I were also doubting about what desired behaviour should be in this case. I think it makes to discuss this later. Should I open a team discuss issue for this? |

This test indexes 150 documents. In case the test index has a high number of segments, it can happen that no documents get sampled. I think this is expected behaviour in this case.
A more detailed explanation of how this failure can happen: #89818 (comment)
This commit adds a special case for this situation, by expecting other counts to be 0 if sampled doc count is 0 as well.
Closes #89818
