As with the previous evaluation, most users were not sure what made them choose the words they did. Two users said that they didn't know and four said something to the effect that that was the subject area or that that was the area they were doing research in. Two users said that they had used keywords. The term ``keyword'' is used to refer to special index terms in the LBS Tinlib system --- these two users obviously assumed that ENQUIRE worked in the same way.
