Comments

Overall looks good, and benefits from using the accessible EUI components when possible. Some notes:

• Machine learning Search filter should give temporal context, i.e. number of results returned and how the user's actions in the search box affects the results table. but I didn't make an issue here because I think it should be rolled up into EUI's component.
