The first concern is,and continues to be,discussed by researchers and practitioners.Users are always looking for better and more efficient ways of finding and filtering information to satisfy their particular needs.Existing search
and retrieval engines provide more capabilities today then ever before,but the information that is potentially available continues to grow exponentially.Web page designers have become familiar with ways to ensure that existing search engines find their material first,or at least in the top 10 to 20 hits
This information may or may not be what the users really want.Thus,the search engines,even though they have now become sophisticated,cannot and do not provide sufficient assistance to the users in locating and filtering out the relevant information that they need (see Jensen,2002; Lawrence & Giles,1999).The second area,efficient use of resources,especially labor,continues to be researched by both practitioners and researchers (Jentzsch & Gobbin,2002).
