Frequency Search is a Chrome extension developed by Tan Kan, available for free in the Browsers category under Add-ons & Tools subcategory. This tool simplifies the process of searching multiple keywords with a common prefix on Google. It allows users to select a specific term, right-click, and initiate a search with predefined keywords automatically added. For instance, when reading about "One Piece," users can easily search for related terms like "One Piece Sanji" or "One Piece Chopper" by simply selecting the character's name. Frequency Search streamlines the search process by automatically including the common prefix, enhancing efficiency for users conducting frequent searches.
