title: Comparison: DB Full Text search to Search engine (Lucene)
body: <p>With stackoveflow.com in perspective (team of 2-3 engineers building a website project intended to scale) does it make sense to spend effort early in the process of development to build a search based on Lucene/Autonomy… as opposed to a database based full text search.  </p>
  
  <p>Pros/Cons:<br>
  With a mature Lucene implementation like nutch or autonomy, the cost of moving to Lucene (which is inevitable) at a later stage is negligible.<br>
  In large volumes adding additional index servers (say with nutch) to maintain the growing search index is relatively easy.<br>
  With a Lucene implementation I’ll mostly likely need an additional server to main the in-memory index (much early in the process of scaling).  </p>
