Alkaline provides a pool of threads for the search operations. This pool can have a maximum of MaxSearchThreads threads. New jobs are added to a queue of MaxSearchQueueSize elements. As a new job arrives and all threads a busy, at least one new thread will be created as long as the thread pool size is below MaxSearchThreads . Optionally RampupSearchThreads will be created in addition to service anticipated load. Each search thread will die if idle for over MaxSearchThreadIdle seconds.
This option was added in version 1.4.0423.0.
