Sun Java System Web Server 6.1 uses a Java-based search engine that supports full-text indexing and searching of documents in all character encodings that the underlying Java VM supports. The default encoding for the documents can be specified at the time of creating a search collection. For HTML documents, the indexer tries to deduce the encoding from the HTML metatags and if it cannot, falls back to use the default encoding.
The search interface is based on JSP tag libraries and can be customized and localized in any language and encoding that you wish. The tag libraries are listed in the Sun Java System Web Server 6.1 Programmer’s Guide to Web Applications. For more information, see Customizing the Search Query Page.
