The DRE uses high-performance matching algorithms to identify patterns within text that can then be matched with similar patterns from other data sources. The identified patterns, also known as concept agents, can facilitate finding similar, relevant patterns by learning which search hits the user prefers.
For more information about setting up and configuring the server and automatic indexing utility, see Appendix C, “Setting Up Automatic Indexing and Search Functionality.”
Search portlets call search EJB functions and get queries executed in the DRE. These search portlets allow you to execute a search across multiple sites at one time and to show the search results from each site to users.
After you install and configure Enterprise Portal, verify that the DRE is properly configured and running by accessing the following URL from your browser:
http://<DREHost>:<DREPort>/qmethod=v
where DREHost is the name of the machine on which the DRE was installed, and DREPort is the port on which the DRE is configured to listen. By default, the DRE is configured to listen on port 8500 for Solaris and port 2000 for Windows. You should see a window similar to the one shown in Figure D-2.
