Bookmarklet code for performing the same search you are already doing but on a different engine. Example: I search for 'shoes' on DuckDuckGo but I want to see if Bing or Google have more/better results.

searchItBookmarklet.js

(function(){
  'use strict';

  var engines = {
    bing: 'https://www.bing.com/search?q=',
    duckduckgo: 'https://duckduckgo.com/?q=',
    google: 'https://www.google.com/search?q='
  };
  
  var engine = engines.duckduckgo; // Change to specify a different search engine
  
  var query = document.location.search.substr(1).split('&');
  var queryParam = '';

  query.forEach(function(q) {
    var split = q.split('=');

    if (split[0] === 'q') {
      queryParam = split[1];
      return false;
    }
  });

  if (queryParam.length > 0) {
    document.location = engine + queryParam;
  }

})();
