    Abstract
    Describes the categories and special features of WWW databases and compares them with traditional databases and presents a state of the art review of the literature on the testing and evaluation of WWW based search engines. Describes the different methodologies and measures used in previous studies and summarizes their findings. Presents some evaluative comments on previous studies and suggests areas for future investigation, particularly evaluation of Web based search engines from the end user's perspective
