Searching a frozen index

Frozen indices are throttled in order to limit memory consumptions per node. The number of concurrently loaded frozen indices per node is limited by the number of threads in the search_throttled threadpool, which is 1 by default. Search requests will not be executed against frozen indices by default, even if a frozen index is named explicitly. This is to prevent accidental slowdowns by targeting a frozen index by mistake. To include frozen indices a search request must be executed with the query parameter ignore_throttled=false.
