At first, it may not be obvious why you'd need such a thing -- after all, your data is nicely filed away in a decent relational database.
While an RDBMS can do a great job of providing transactional CRUD operations on data stored in a relational model, search functions defined in SQL are not always capable of meeting both the functional and non-functional requirements of your projects. There are a number of query types that RDBMSs in general do not support without vendor extensions: Fuzzy queries, in which "fuzzy" and "wuzzy" are considered matches Word stemming queries, which consider "take," "took," and "taken" to be identical Sound-like queries, which consider "cat" and "kat" to be identical Synonym queries, which consider "jump," "hop," and "leap" to be identical Queries on binary BLOB data types, such as PDF documents, Microsoft Word or Excel documents, or HTML and XML documents More disappointingly, SQL search results are not ranked by match-relevance scores.
The SQL standard is simply not intended for full-text querying. Lucene search capabilities, on the other hand, are unlimited. Lucene handles all the queries just mentioned, and more; it also allows you to find text documents similar to other documents through its advanced term-vector query.
For instance, you could search the content of a number of books to find one with content similar to that of Hibernate in Action. The analyzer architecture in Lucene leverages Java's built-in internationalization and localization capabilities, which makes full-text query available for various languages worldwide. Lucene delivers outstanding performance through some innovative techniques, such as an inverted index.
