These are search engines that use proprietary software for crawling, indexing and ranking to create unique search results. What surprised me is that this list is very short. Most search engines just use the technology or search results of other search engines. robably the main reason is that building a search engine is technologically complex, because of the huge size of the Internet and the need to have relevant search results with a very short response time. You need to write complex software and you need a significant amount of capital to invest in network capacity and hardware to create a search engine for the Internet, which contains billions of web pages.<br /><br />I found the following unique search engines:<br /><a href="http://www.google.com/">http://www.google.com</a> (The market leader)<br /><a href="http://www.yahoo.com/">http://www.yahoo.com</a> (Famous search engine)<br /><a href="http://www.bing.com/">http://www.bing.com</a> (New microsoft search engine)<br /><a href="http://www.teoma.com/">http://www.teoma.com</a> (Search engine also used by ask)<br /><a href="http://www.gigablast.com/">http://www.gigablast.com</a><br /><a href="http://www.walhello.com/">http://www.walhello.com</a><br /><a href="http://www.duckduckgo.com/">http://www.duckduckgo.com</a><br /><a href="http://www.searchhippo.com/">http://www.searchhippo.com</a><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/5154716256164121865-5771781527742043741?l=searchengineresearch.blogspot.com' alt='' /></div>walhellonoreply@blogger.com0
