title: Lucene and SQL Server - best practice
body: <p>I am pretty new to Lucene, so would like to get some help from you guys :)</p>
  
  <p>BACKGROUND: Currently I have documents stored in SQL Server and want to use Lucene for full-text/tag searches on those documents in SQL Server. </p>
  
  <p>Q1) In this case, in order to do the keyword search on the documents, should I insert all of those documents to the Lucene index? Does this mean there will be data duplication (one in SQL Server and the other one in the Lucene index?) It could be a matter since we have a massive amount of documents (about 100GB). Is it inevitable?</p>
  
  <p>Q2) Also, each documents has a set of tags (up to 3). Lucene is also good choice for the tag search? If so, how to do it?</p>
  
  <p>Thanks,</p>
