MultiStage

Set MultiStage to True to enable multistage querying for the DAH running in non-mirror mode. A multistage query is processed stage-by-stage across specified VDBs. The specified VDBs serve the query in stages. Each stage is a separate query. DAH stores all results in each stage until sufficient matches are found, and then returns the specified number of results.

You can set the stage information for multistage querying in the [MultiStageQuery] section of the DAH configuration file. Alternatively, you can use the MultiStageTotalStages and MultiStageInfo action parameters.

NOTE: The MultiStageTotalStages and MultiStageInfo action parameters override the DAH configuration parameters.
