How does the search algorithm on stackoverflow work? I need to implement a search functionality in one of my web sites.
                
                A: 
                
                
              
            and as stackoverflow saying:
- You're browsing through questions matching search terms search stackoverflow
 - Search within specific tags by adding them in brackets, like [tag] or [tag-2].
 - Enclose your search in "quotes" to match a phrase.
 - You can narrow your search by using the ~ (near) and - (not) operators before words.*

              Not very well. If you need your site searchable, try adding a Google search box through Adsense (and setting up a sitemap).

              definitely outsource this to Google. It's essentially what we do, since 90% of our traffic is from Google.
