Meilisearch: require all query terms to be matched (#28293)

Previously only the first term had to be matched. That default
Meilisearch behavior makes sense for e.g. some kind of autocomplete to
find and select a single result. But for filtering issues it means you
can't narrow down results by adding more terms.

This is also more consistent with other indexers and GitHub.
