You might be familiar with the tedious manual process of installing new Internet Explorer Search Providers by using the IE Add-ons Gallery: http://www.iegallery.com/en-us/AddOns
However, what if you want to add a search provider which is not listed in the IE Add-ons Gallery such as an alternative search engine such as Dogpile (http://www.dogpile.com/)
Well, fortunately, a developer has created a nifty little website which allows you to do just that and even Install the custom Search Provider to Internet Explorer!
You can create a custom Search Provider by visiting this website: http://www.enhanceie.com/ie/searchbuilder.asp
You simply have to visit the search engine of your choice and search for the word “TEST”. You then simply paste the search results page Url into the appropriate Textbox, provide a name for the custom Search Provider and you will be ready to install your very own custom Search Provider for Internet Explorer!
NOTE: While the site states that it is primarily made for targeting Internet Explorer 7, I have tested this with Internet Explorer 11 on Windows 8.1 and it works just fine!!
