User story

As adata analyst,
I wantbe able to have more than 10.000 search results, and monitor them,
so that I won't have to retrieve all indices and implement cursoring in elastic search myself.

Acceptance criteria

1. Should be able to respond with more than 10k query results. Example Query: https://zoek.openraadsinformatie.nl/?zoekterm=%22%5C%22antea+group%5C%22%22
2. Ofcourse search results should be able to be limited to only contain document id, and a last-updated field, instead of included with _sources.
3. Last updated field would be interesting for allowing data users to keep up to date.
