      • onNewContext

        default void onNewContext​(SearchContext context)
        Executed when a new search context was created
        Parameters:
        context - the created context

      • onFreeContext

        default void onFreeContext​(SearchContext context)
        Executed when a previously created search context is freed. This happens either when the search execution finishes, if the execution failed or if the search context as idle for and needs to be cleaned up.
        Parameters:
        context - the freed search context

      • onNewScrollContext

        default void onNewScrollContext​(SearchContext context)
        Executed when a new scroll search SearchContext was created
        Parameters:
        context - the created search context

      • onFreeScrollContext

        default void onFreeScrollContext​(SearchContext context)
        Executed when a scroll search SearchContext is freed. This happens either when the scroll search execution finishes, if the execution failed or if the search context as idle for and needs to be cleaned up.
        Parameters:
        context - the freed search context

      • validateSearchContext

        default void validateSearchContext​(SearchContext context,
                                   TransportRequest transportRequest)
        Executed prior to using a SearchContext that has been retrieved from the active contexts. If the context is deemed invalid a runtime exception can be thrown, which will prevent the context from being used.
        Parameters:
        context - the context retrieved from the active contexts
        transportRequest - the request that is going to use the search context
