      com.raritantechnologies.federated.FederatedQueryProcessorFilter

All Implemented Interfaces:

IQueryProcessor

public class FederatedQueryProcessorFilter

extends QueryProcessorFilter

Enables a set of sources to be explicitly federated to combine results from different sources.

XML Configuration Template:

   <SourceType name="[ name of FederatedQueryProcessorFilter source]"
             type="QueryProcessorFilterSource"
             sourceFactoryClass = "com.raritantechnologies.searchApp.QueryProcessorFilterFactory"
             filterClass  = "com.raritantechnologies.federated.FederatedQueryProcessorFilter"
             inputSources  = "[ comma separated list of names of SearchSources that collects the results to sort ]"  >

       <!-- Alternatively can specify sources here -->
       <Source name="search source name" securityManager="[ optional security manager name ]" />
