I don't know of any conservative search engines, but I have found a way to limit the search returns from being completely liberal biased. I use search term exclusions, and this will exclude any site listed in my list. You can add to it or remove things from it but I keep a list of my search terms to exclude in a document on the desktop, and copy and paste them into my search engine after I enter my primary search term. You should try it both ways to see the difference. Search for President Trump, then do the same search and copy and paste a list of exclusions like those below. Simply put a - in front of any word to exclude. Each time I find a liberal website I add it to the list. My growing list :
