title: Big website architecture question
body: <p>For a website that should allow searching based on a few filters on about 100 millions records, is it good enough to pick <a href="http://lucene.apache.org/solr/" rel="nofollow">Solr</a> for searching? </p>
  
  <p>The website would be written in C#, (asp.net mvc), the backend database with user data and shopping cart should be SQL Server 2008R2. Does it scale ok for 10 million users?
  Other stuff that should be used: Memcached, HAProxy probably... </p>
