Meilisearch `search` returns a limit of 1000 documents on search

[spaenleh]

For performance, meilisearch returns a limit of 1000 documents on search.

We currently use the totalHits value in the search result to display in the header "Search among XXX resources" this always shows 1000 since we have surpassed 1000 published resources.

We should probably either increase the limit (but that will hit performance), or rely on a looser count (maybe updated once a week when we re-index ?)

Mentioning @pyphilia for awareness.
