1. Matt Honeycutt @matthoneycutt Adding powerful search capabilities to your application with Lucene.NET and NHibernate Search

2. What should we do?

3. Our application Something completely revolutionary!

4. Solution Overview

5. NHibernate Primer • Object-relational mapper • “Use it whenever you need to access a relational database” – Oren “Ayende” Eini

6. NHibernate Primer • Object-relational mapper • “Use it whenever you need to access a relational database” – Oren “Ayende” Eini <hibernate-mapping package="org.hibernate.tutorial.domain"> <class name="Event" table="EVENTS"> <id name="id" column="EVENT_ID"> <generator class="native"/> </id> <property name="date" type="timestamp" column="EVENT_DATE"/> <property name="title"/> </class> </hibernate-mapping> <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2" > </hibernate-configuration> <property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property> <class name="Cat" table="Cat"> <id name="Id"> <generator class="identity" /> </id> <property name="Name"> <column name="Name" length="16" not-null="true" /> </property> <property name="Sex" /> <many-to-one name="Mate" /> <bag name="Kittens"> <key column="mother_id" /> <one-to-many class="Cat" /> </bag> </class> <property name="connection.connection_string">Server=(local);Initial Catalog=dbname;User Id=user;Password=********</property> <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property> <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>

8. Configuring NHibernate using Fluent NHibernate

9. What’s the problem? “As a user, I want to be able to find interesting blog posts by specifying one or more keywords I’m interested in. The blog should display a list of blog posts sorted by relevance.”

10. How can we add search capabilities?

11. I don’t know if I LIKE this…

12. SQL Server Full-text indexing

13. What’s about this “Lucene” thing?

14. Lucene Overview ? Searching Indexing Query Parser Document Index Searcher Analyzer Index Reader Index Writer Directory (Index)

15. Indexing and Searching with Lucene.NET

16. That’s a lot of code, isn’t there an easier way?

17. NHibernate.Search - Indexing SQL Database NHibernate Entity Add Update Delete Post-Insert Post-Update Post-Delete NHibernate.Search Lucene.NET Directory

18. NHibernate.Search - Querying IFullTextSession ISession ISession NHibernate Lucene.NET SQL Database Directory

19. Configuring NHibernate.Search

20. Using NHibernate.Search

21. So what’s left?
