I recently updated our Elastic instances to 7.15.2. I am seeing mixed results when applying filters in Discover. For example, when filtering out a host on the agent.hostname field (i.e. 'NOT agent.hostname: example\_host), not all instances of the host are removed. If I filter for only that host (i.e. agent.hostname: example\_host), the filter appears to work correctly and only show results for 'example\_host'.

**Scope**  
This appears to only affect the logs-\* datastream coming from Elastic Agent instances. The agent.hostname field filters correctly on other Beats indices. I also only see this behavior on that specific field for logs-\*.

Could you share with us:

1. Both correct and incorrect requests that are being made from Discover: `Discover > Inspect > request`

2. Result of `GET /_resolve/index/logs-*` in Dev tools. Both for `logs-*` and for any other working as expected pattern

3. Result of `GET logs-*/_field_caps?fields=agent.hostname` in Dev tools. Both for Both for `logs-*` and for any other working as expected pattern
