摘要： This invention provides the data network user with an interactive search engine environment that helps him focus on the object of his search. Through a powerful graphical user interface (GUI), the user is provided with terms closely related to what he is looking for, even when he has no prior knowledge of the subject or its terminology. The user is also provided with suggested terms that should be excluded from the search because of the high probability of interfering with the search. The contribution of each term to the search progress is explained to the user. The invention then enables the user to build complex queries combining the related terms in a visual and simple way that facilitates the search process and saves time. This invention allows the user to create a detailed, precise, and longer search query then is customarily executed today.
