We propose that such can be used to elicit terms use in query expansion and as follow-up when ambiguous queries are initially posed. design feedback form obtain additional users, administer after initial querying, create series experimental runs based on obtained form. Results demonstrate was successful at significantly improved retrieval performance. Our results further strong relationship between length
