8. A computer implemented method for generating search queries using visual manipulation of search terms to facilitate a search process over a data network, comprising: receiving an initial search query as a visual representation, said visual representation includes at least one search term as an initial graphical icon; scanning over said network and, based on said scan, providing at least a list of related terms associated with said initial search query, wherein said related terms are being provided as additional graphical icons, wherein the scanning includes obtaining relationships involving said related terms and data entities at different locations in said data network, and organizing said related terms, said relationships, and said data entities in at least one data structure that represents said relationships in said data network, wherein the data structure is organized, based on at least one of data network analysis and expert knowledge, wherein the data entities in said data network are analyzed in accordance with statistical correlations of word frequencies, location, and dates within the data network; enabling a user to visually manipulate said initial search query by visually placing one or more of said initial graphical icon and said additional graphical icons respective of one or more related terms to be included in a new refined search query in a plurality of graphical operators, each of said plurality of graphical operators applies a different operation on related terms placed therein, wherein said visual manipulation results in a new visual representation of graphical icons respective of said one or more related terms and interrelationships of said graphical icons with said plurality of graphical operators; and generating said new refined search query by applying said plurality of graphical operators on said one or more of related terms, thereby modifying said initial search query according to said visual manipulation.
