Exact Search

I know that many domainers use the “Exact Search” theory when they register a domain name or decide to continue renewing their domains for that matter.

For those who are wondering what is an “Exact Search“?, it is when you search for a particular keyword, phrase or domain name in a search engine while using the quotation tags. And as defined on the web, it is a Non-truncated search, giving a hit list with terms exactly matching the entered search term.

My questions are… How many “Exact Searches” does a domain name need before you deem it sufficient and would consider it to be a decent domain name with potential value? I have heard that, the more the better. So 400,000 search results would be better than 40,000 search results, right? Or does that mean there is more competition?

Please share your knowledge and advice on this subject.
