6 Oracle Ultra Search

This chapter summarizes release note issues associated with Oracle Ultra Search.

The following sections are included in the chapter:

6.1 What's New in Ultra Search

Oracle Ultra Search is a high-level search component supplied with the Oracle Collaboration Suite that you can use to search across other Oracle Collaboration Suite components, corporate Web servers, databases, mail servers, file servers, and Oracle9iAS Portal instances. It uses information you provide to crawl through the various disparate repositories of information in your company searching for documents according to your search criteria. Oracle Ultra Search searches over 150 proprietary document types.

This release of Ultra Search includes the following features:

6.2 Ultra Search Welcome Page

The Ultra Search welcome page is now at the following location:

http://host:port/ultrasearch/welcome/

Where host is the host used to install the middle tier.

6.3 Default Ultra Search Instance

The Ultra Search installer creates a default out of the box Ultra Search instance based on the default Ultra Search test user. So, you can test Ultra Search functionality based on the default instance after installation.

The default instance name is WK_INST. It is created based on the database user WK_TEST. The default user password is WK_TEST. For security purposes, WK_TEST is locked after the installation.

The administrator should login to the database as DBA role, unlock the WK_TEST user account, and set the password to be WK_TEST (the password expires after the installation).

If the password is changed to anything other than WK_TEST, then you must also update the cached schema password using administration tool Edit Instance page after you change the password in the database.

The default instance is also used by the Ultra Search sample query application. Make sure to update the data-sources.xml file.

6.4 Document Relevancy Boosting Limitations

You can override the search results and influence the order that documents are ranked in the query result list with document relevancy boosting. This can promote important documents to higher scores and make them easier to find.

Relevancy boosting has the following limitations:

6.5 Translations for Complete Sample Query Application

The Ultra Search Complete Sample Query Application is translated into the same set of languages supported in Oracle Collaboration Suite Release 2.

6.6 Dynamic Page Indexing Control

For Web data sources, there is a new option to index or not index dynamic pages. The default value is Yes, so dynamic URLs are crawled and indexed.

For data sources already crawled with this option, setting Index Dynamic Page to No and recrawling the data source removes all dynamic URLs from the index.

Some dynamic pages appear as multiple search hits for the same page, and you may not want them all indexed. Other dynamic pages are each different and need to be indexed. You must distinguish between these two kinds of dynamic pages. In general, dynamic pages that only change in menu expansion without affecting its contents should not be indexed. Consider the following three URLs:

http://itweb.oraclecorp.com/aboutit/network/npe/standards/naming_convention.html

http://itweb.oraclecorp.com/aboutit/network/npe/standards/naming_
convention.html?nsdnv=14z1

http://itweb.oraclecorp.com/aboutit/network/npe/standards/naming_
convention.html?nsdnv=14

The question mark ('?') in the URL indicates that the rest of the strings are input parameters. The duplicate hits are essentially the same page with different side menu expansion. Ideally, the same query should yield only one hit:

http://itweb.oraclecorp.com/aboutit/network/npe/standards/naming_convention.html

Dynamic page index control applies to the whole data source. So, if a Web site has both kinds of dynamic pages, then you need to define them separately as two data sources in order to control the indexing of those dynamic pages.

6.7 Cookie Support

If you register authentication information for a data source, then the Ultra Search administration tool automatically turns on cookie support. You can override this and turn cookies support off.

6.8 Crawler Cache Deletion Control

During crawling, documents are stored in the cache directory. Every time the preset size is reached, crawling stops and indexing starts. In previous releases, the cache file was always deleted when indexing was done. You can now specify not to delete the cache file when indexing is done. This option applies to all data sources. The default is to delete the cache file after indexing.

6.9 Set the Environment to Use the INSO Filter

The Ultra Search crawler uses the Oracle Text INSO filter ctxhx, which requires that your shared library path environment variable contain the $ORACLE_ HOME/ctx/lib path. Without that, filtering fails for any binary document.

During installation, the Oracle Installer automatically sets the variable to include $ORACLE_HOME/ctx/lib. However, if, after the installation, you restart the database, then you must manually set your shared library path environment variable to include $ORACLE_HOME/ctx/lib before starting the Oracle process. You must restart the database to pick up the new value for filtering to work.

For example, on UNIX set the $LD_LIBRARY_PATH environment variable to include $ORACLE_HOME/ctx/lib, and on Windows set the %PATH% environment variable to include %ORACLE_HOME%\bin.

6.10 Known Bugs

Table 6-1 Known Bugs

Bug No. Description
2881313 A Web Provider error occurs when registering the Ultra Search portlet.

Workaround:

Update the following so that the full path of the directory is specified, without using the %ORACLE_HOME% environment variable:

%ORACLE_HOME%\j2ee\OC4J_Portal\applications\jpdk\jpdk
\WEB-INF\services.xml

Change the value of option key=FileProviderGroupMgr.dir.
