"Oracle Essentials: Oracle Database 11g"

Oracle database version
8.1.7 introduced Ultra Search, leveraging Oracle Text. Today, Ultra Search is
included with the Oracle database and the Oracle Application Server.
Ultra Search gathers information using a Java process crawler started by Oracle on a
set schedule. The crawler indexes the documents residing on various servers using
Oracle Text, and then stores this information in an Oracle database. The Ultra
Search administration tool is a J2EE-compliant web application. Application builders
can invoke Ultra Search using PL/SQL or Java procedures and use the APIs to
make crawler results ???searchable.???
In Oracle Application Server, Ultra Search is located in the metadata repository.
Application Server users can search and receive a list of results through a portlet that
can be accessed through Oracle Portal.
In a secure search, document retrieval is based on user access rights. An access control
list (ACL) is evaluated during such a secure search. The ACLs are stored in XML
DB.
Ultra Search requires management skills commonly found where Oracle
databases and Application Servers are deployed.
