3 Questions: Versions of Lucene.NET, Replacing DB and Successful
Cases
Hi, all,
I have three questions about Lucene.NET as follows.
1) I am using Lucene to index my crawled Web data. Originally, MySQL
was used. I plan to replace it with Lucene.NET. Anybody has such
experiences? I really worry about the performance and the load on the
machines.
2) What's the latest version of Lucene.NET? The link,
http://incubator.apache.org/lucene.net/, is the only location to get
it?
3) Any successful cases?
Thanks,
LBLabs

Using NHibernate.Search : The MySql database (i'd prefer sql server
but that's up to you) stores the data. when you insert, update data -
lucene indexes it, stores the index in the traditional format (index
files on disk). The index holds a reference to the location of the
actual data in the db - so retrieving data is no faster or slower than
using file based storage and retrieving is no faster or slower than
standard db reading.

I think the performance of MySQL is not as high as Lucene when
searching by any possible keywords. And, MySQL or relational databases
look cumbersome.
How do you think about that?
Thanks,

Not sure about the other questions but why not use nhibernate.search
and keep ur data in mysql?
