This chapter provides a brief description about the new features available in Oracle Secure Enterprise Search (Oracle SES) 11g Release 2. It also provides pointers to additional information.
New features for administrators:
Document Attributes report. You can now view all the document attributes defined in Oracle SES, along with their data sources and search attributes, in the Administration GUI by navigating to the Global Settings - Document Attributes page. See also "Overview of Attributes".
Trusted web and crawler services support. The searchadmin script now supports SSL connections.
Disabled features in this release:
The Oracle SES 10g Administration API is deprecated in this release (searchadminctl and the associated Web services). The Oracle SES 11g Administration API replaces it. The following public Web services are disabled in this release:
oracle.search.admin.ws.client.SearchAdminClient
The following are the operations provided by this Web service:
getEstimatedIndexFragmentation
getSchedules
getScheduleStatus
optimizeIndexNow
startSchedule
stopSchedule
login
logout
oracle.search.admin.ws.client.Schedule
oracle.search.admin.ws.client.ScheduleStatus
New features for administrators:
Oracle SES is installed with Oracle Fusion Applications. You can install Oracle Database and WebLogic Server at the same time, or you can install Oracle SES into an existing Database 11.2.0.2 or WebLogic Server 11.1.1. Refer to the Oracle Fusion Applications Installation Guide.
Installation topology changes:
The Oracle SES middle-tier software bits are installed in Fusion Middleware Home (MW_HOME). ORACLE_HOME for is named ses by default.
The Oracle SES middle-tier components are deployed in the SES cluster in the Fusion Middleware Common Domain. This change improves scalability.
The crawler runs on the Oracle Enterprise Scheduling System (ESS) cluster in the WebLogic Common Domain. Be sure to provide sufficient resources in this cluster for the crawler. See "Secure Search in Oracle Fusion Applications".
The Oracle SES schema is installed in the Fusion database (either a single instance of Oracle Database or Oracle RAC). Oracle RAC enables a single database to run across a cluster of servers, making it highly fault tolerant, scalable, and available. See "Supporting Failover in Oracle RAC".
Oracle SES uses these default tablespaces: SEARCH_DATA, SEARCH_INDEX, and SEARCH_TEMP. You or your Oracle Database administrator can create additional tablespaces before initiating the first crawl, and you can add data files and temp files to the existing tablespaces any time after Oracle Database is installed. See "Increasing Data Storage Capacity".
Upgrading from previous releases of Oracle SES is not supported.
The following configuration files have been removed: search.properties, search.config, searchctl.conf, crawler.dat, and ranking.xml. The configuration parameters from these files were moved to Oracle Database. Some parameters can be modified using the Administration API, while others are not configurable.
Schedules are managed by Oracle Enterprise Scheduling System (ESS). See "Crawler Schedule".
The RSS crawler is recoverable when it is used in control feed mode. On restart, the crawler resumes processing from where it was interrupted.
XML data feeds do not have a default content type. If the content type is not specified explicitly, then Oracle SES automatically detects the data type. Some filtering overhead is incurred in this process.
Debug mode is turned on using either Oracle Enterprise Manager or the WebLogic Server Administration Scripting Tool. See "Turning On Debug Mode".
Faceted navigation can be configured through the Administration API. See "Providing Faceted Navigation".
Wildcard queries are not enabled by default. You can turn on wildcards by modifying the queryConfig object using the Administration API. See Oracle Secure Enterprise Search Administration API Guide.
New features for end users:
Oracle SES supports crawling of the following additional document formats:
Microsoft Office 2008 for Mac. You can search for Word, Excel, and PowerPoint files.
PDF version 1.7
In addition, there are some enhancements to how Oracle SES searches the following document formats:
Microsoft PowerPoint 97- 2003: You can now search files that are set to Read Only.
Microsoft Office 2007: Support for SmartArt.
Disabled features in this release:
