Distributed Action Handler 12.12

# Multi-Stage Query Configuration Parameters

The Distributed Action Handler supports multi-stage querying in non-mirror mode. You can use the `[MultiStageQuery]` section to configure the stage information for multi-stage querying.

A multi-stage query is processed in stages across specified VDBs. The specified VDBs are used to serve the query in stages, until the required number of results are found.

For example:

    [MultiStageQuery]
    Stages=3
    0=db0
    1=db1
    2=db2,db3

NOTE: To enable multi-stage querying, use the `MultiStage` or `MultiStageMinResults` parameters with `Query` or `SuggestOnText` actions. See IDOL Server help for details of action parameters.
