update index in Lucene.NET

Jul 17, 2012 at 11:50 AM

Hi,
 
I am doing a POC on Search using Lucene.NET.
 
I fire a stored procedure which fetches around 50000 records from the database.
Thses records I put in the Lucene Index.
 
Now when the records in database changes, how to update the Lucene index.
Deleting the entire previous indexed and creating a new one will take a lot of time.
 
I want to append the new records from the database to the existing index.
 
How can I achieve this.
Any ideas ???
 
Thanks,
Aneesh
