java.lang.Object
  com.raritantechnologies.searchApp.QueryProcessorFilter
      com.raritantechnologies.searchApp.queryFilters.CachingQueryProcessorFilter

All Implemented Interfaces:

IQueryProcessor

public class CachingQueryProcessorFilter

extends QueryProcessorFilter

Caching Search source: returns the results of the previous query if the current query is identical.
