This patent is generally related to search. Techniques are disclosed for textual search based on “interactive search refinement based on features similarity” (ISRFS) having a graphical user interface (GUI) to allow the user to easily control the affinity quality and the search process. The tool retrieves the textual items having high affinity to the user’s searched item from a repository of textual data, refine the search results based on semantic similarity, automatically extracted features, and a graded semantic scale such as semantic affinity metric (SAM). The technology may be implemented in search algorithms, search engines, etc.
