An associative text search and retrieval system uses one or more front end processors to interacting with a network having one or more user terminals connected thereto to allow a user to provide information to the system and receive information from the system. The system also includes storage for a plurality of text documents, and at least one processor, coupled to the front end processors and the document storage. The processor(s) search the text documents according to a search request provided by the user and provide to the front end processor a predetermined number of retrieved documents containing at least one term of the search request. The retrieved documents have higher ranks than documents not provided to the front end processor. The system includes a display for displaying a window of text of one of the retrieved documents, the window having a highest score of all possible windows of the retrieved document, the score varying according to the number of search terms in the window and the number of search terms in the window preceded by a different search term in the window.
