Hibernate Search !!

I read Hibernate Search Book about 2 chapter today
They explain the Hibernate Search module extends the basis of the Lucene and Solr library
I 'm very interesting Because I read before Lucene and Solr little.
I wish for practicing Lucene or Solr library more.
Perhaps I have other opinion related Lucene and Solr

key Sentense is
The three gole of using the Hibernate Search is

1. structural mismatch
2. synchrozination mismatch
3. retrieval mismatch


That's Good !!
