Internet searches sometimes provide search results referencing webpages that do not contain all search term elements submitted by a user. The user may then click on such Internet search results where referenced webpages, and/or their descendants, do not contain important search term elements. Also, advertisements may be placed on search results webpages that relate to the user's search term elements, even though there may be search terms missing in referenced and/or descendant webpages. The present invention is directed to: annotating Internet search results to indicate missing search term elements on referenced and descendant webpages; optionally filtering out search results referencing webpages with missing terms; and showing advertisements related to search term elements. This annotation and/or filtering facilitates the user to avoid clicking on an Internet search result where the user's search term elements are not present on referenced and/or descendant webpages, thereby preventing wasted time and speeding the search process.
