lucene.net

Our product consists of multiple applications, All using Lucene. 2 of the applications I am involved with have Lucene indexes of about 3 GB and 12GB. Another team is building an application, for which they estimate the LUCENE INDEX size to be close to 1 Terabyte. New documents are added to the indexes every 15 days approx. We do not have any apparent performance issues with the current applications. So my question is

SHould we be using Solr now?

When should one stop using Lucene and graduate to Solr?

Any disadvantages/problems for using Solr?

The client applications are made in ASP.Net, but I assume they will be able to use a solr server using solrnet
