Rails 2.x suggestions to add search capabilities to a model

Looking to add search capabilities to a model for reporting purposes. I was thinking searchlogic, Do you guys have any other suggestions for an application using rails 2.x?

-Thanks

Sphinx using UltraSphinx Solr using the plugin acts_as_solr

Both are really easy to get up and running. I like Solr because it will auto-index your model when new records are added.
