Search Toolkit Book for IQueryDataSource

#include <gui/objutils/query_data_source.hpp>

This is an abstract interface for any datasource that wants to support queries using CQueryParseTree and CQueryExec. This interface supports searching the data source for a spcified string (when parsing is not being used) and supports the creation of a query execution object that is tailored for that data source. This interface also allows the user to set and clear a set of selected results for the data source.
