title: Search Engine - Lucene or Solr
body: <p>We need to integrate a search engine in our Product Catalog management software. the catalog is expected to have more than 4-5 mn. records with relational data spread over several tables. Our dev platform is Asp.Net 3.5 and we have done some pre-liminary work on Lucene, found it to be good. However, we just came to know of Solr and was looking for some practical tips to compare Lucene &amp; Solr from implementation, timeline, regular maintenance, performance, features perspective. Any guidance or pointers would be really helpful. Thanks. </p>
