    In some cases as one shared with issue #1099, the maxConcurrentSearchRequests
    was chosen as 0 which
    will compute the final value during execution of the
    request based on processor counts. When this
    computed value is less than
    number of search request in msearch request, it will execute all the
    requests
    in multiple iterations causing the failure since test will only wait for one
    such
    iteration. Hence setting the maxConcurrentSearchRequests explicitly to
    number of search requests
    being added in the test to ensure correct behavior

* __Part 1: Support for cancel_after_timeinterval parameter in search and msearch request (#986) (#1085)__

    [Sorabh](mailto:sorabh@apache.org) - Thu, 12 Aug 2021 13:52:28 -0400


    * Part 1: Support for cancel_after_timeinterval parameter in search and msearch
    request
     This commit introduces the new request level parameter to configure the
    timeout interval after which
    a search request will be cancelled. For msearch
    request the parameter is supported both at parent
    request and at sub child
    search requests. If it is provided at parent level and child search request

    doesn't have it then the parent level value is set at such child request. The
    parent level msearch
    is not used to cancel the parent request as it may be
    tricky to come up with correct value in cases
    when child search request can
    have different runtimes
     TEST: Added test for ser/de with new parameter
     Signed-off-by: Sorabh Hamirwasia <sohami.apache@gmail.com>

    * Part 2: Support for cancel_after_timeinterval parameter in search and msearch
    request
     This commit adds the handling of the new request level parameter and schedule
    cancellation task. It
    also adds a cluster setting to set a global cancellation
    timeout for search request which will be
    used in absence of request level
    timeout.
     TEST: Added new tests in SearchCancellationIT

     Signed-off-by: Sorabh Hamirwasia <sohami.apache@gmail.com>

    * Removing the search.enforce_server.timeout.cancellation cluster setting and
    just keeping search.cancel_after_time_interval setting with request level
    parameter taking the precedence.
