@ -27,6 +27,8 @@ data structures in memory, frozen indices consume much less heap than normal
indices. This allows for a much higher disk-to-heap ratio than would otherwise
be possible.
You can freeze the index using the <<freeze-index-api, Freeze Index API>>.
Searches performed on frozen indices use the small, dedicated,
<<search-throttled,`search_throttled` threadpool>> to control the number of
concurrent searches that hit frozen shards on each node. This limits the amount

not intended for high search load. It is possible that a search of a frozen
index may take seconds or minutes to complete, even if the same searches
completed in milliseconds when the indices were not frozen.
To make a frozen index writable again, use the <<unfreeze-index-api, Unfreeze Index API>>.
