Returns the stats, including group specific stats. If the groups are null/0 length, then nothing is returned for them. If they are set, then only groups provided will be returned, or _all for all groups.

onPreQueryPhase

public void onPreQueryPhase(SearchContext searchContext)

Description copied from interface: SearchOperationListener

Executed before the query phase is executed

Specified by:

onPreQueryPhase in interface SearchOperationListener

Parameters:

searchContext - the current search context

onFailedQueryPhase

public void onFailedQueryPhase(SearchContext searchContext)

Description copied from interface: SearchOperationListener

Executed if a query phased failed.

Specified by:

onFailedQueryPhase in interface SearchOperationListener

Parameters:

searchContext - the current search context

Parameters:

readerContext - the created context

onFreeReaderContext

public void onFreeReaderContext(ReaderContext readerContext)

Description copied from interface: SearchOperationListener

Executed when a previously created reader 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.

Specified by:

Description copied from interface: SearchOperationListener

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.

Specified by:

onFreeScrollContext in interface SearchOperationListener

Parameters:

readerContext - the freed search context
