// Unlike chat view, sorting by `timestamp` is not necessary but slows down the query by

// To speed up incremental search, where queries for few characters usually return lots
// of unwanted results that are discarded moments later, we added `LIMIT 1000`.
// According to some tests, this limit speeds up eg. 2 character searches by factor 10.
// The limit is documented and UI may add a hint when getting 1000 results.
