Multi-search-engine addon. Even no-query-interface website as search engines

Big Search is a browser extension (Firefox+Chrome) to use / switch any one or multiple search engines. Source code on Github <https://github.com/garywill/BigSearch> . Already has 50+ search engines build-in and working. Still keep adding more. Besides basic features, it is with some special technical features also. For example: some websites don't provide GET/POST interface to public (so-called Ajax-only websites). Visitor need to open their page and input, then they show search results on page via Ajax. Big Search works with those. Can turn such Ajax-only websites into search engines and add them to browser. Chrome Extension API doc ( https://developer.chrome.com/docs/extensions/reference/ ) is one of such Ajax-only websites. That's a simple one. There're more such websites with more complicated js involved to do search, which will be figured out in the future plan. Big Search repo on Github : https://github.com/garywill/BigSearch
