ISR11 The SMART System -- Retrieval Results and Future Plans chapter G.

It is not expected that the basic evaluation results already obtained will be substantially affected by these new environments; however, additional information will be gained, particularly about operational conditions, which will hopefully be useful in improving the design of actual automatic information systems.
