Abstract There are many search engines which can rank the search result considering the proximity of search terms, and that functionality is called Proximity Ranking. In these Proximity Ranking, the proximity among all search terms are calculated from the distance between each pair of terms, therefore the proximity score tends to be less accurate in case the number of search terms is more than two. This invention provides the effective method to evaluate the proximity of search terms in case of more-than-two search terms. Details "Common Technologies and their Problems"
