Restrictions on the number of queries per second for the “Russian” search type

For the “Russian” search type, additional limits may be applied to the number of requests sent per second (RPS).

Allowed number of requests per second ($rps\_restriction$) depends on the hourly limit ($hourly\_limits$) and is calculated using the formula:
$rps\_restriction = \frac{hourly\_limits}{2000}$

Exceeding this threshold might lead to errors (up until the next second).
