Lucene Based Database Search Engine

Question

I plan to add a search function in my web application. I am using the Struts 2 framework for an application, and the elements that will be found will be stored in a relational database. To achieve a full-text search, I doubt:

• For a search-based database, I should use only lucene or some other Luncene-based utility like Solr, luSql, Compass, etc.
• In the case of Solr, it can be embedded in a web application rather than deploying it as a maritime WAR.
• Is solr used to search for relational databases or just file systems.
