AOLserver Full Text Features

The full-text features of AOLpress and AOLserver use the Illustra "object-relational" database management system (DBMS) provided with AOLserver. Illustra is a complete relational database management system that supports industry standard Structured Query Language (SQL), as well as an object-oriented DBMS that allows the creation of new data types, access methods, and functions.

• AutoLinking--Any page stored on a server is available for AutoLinking. AOLserver searches pages on the same server or other servers and provides you with suggestions for possible links from the current page to pages on the server you chose. AutoLinks are described in the AOLpress User's Guide.

• Indexing--AOLserver stores all pages published to the server. Also, every time you save a page to the server, AOLserver processes the page and creates a searchable index from the text of the page. The URL for the page, along with this full-text index, is stored in the ns_pages_server-name table. You can then search the server based on the information in the full-text index. See the "Search the AOLserver" section for more information.

• Archiving--One advantage of AOLpress is that it is much easier and faster to make changes to your World Wide Web pages. As a result, you might want the ability to go back to a previous version of a page. You can run AOLserver with archiving on or off. By default, archiving is turned off, because it takes space to store previous versions of pages and CPU time to manage the archive. If archiving is on, the previous version of the page is saved every time you write a new version to the server, and an archive log is written to the ns_archives_server-name table. See the "Archive and Restore Pages" section for more information.
