A Web source enables users to search a Web site. The following procedures identify the basic steps for setting up a Web source using the Oracle SES Administration GUI. For more information on each page, click Help.
Oracle SES is configured to crawl Web sites on the intranet within the corporate fire wall. To crawl Web sites on the Internet (external Web sites), Oracle SES requires the HTTP proxy server information. See the Global Settings - Proxy Settings page.
You should review the default crawling parameters before you start crawling Internet sources.
To create a Web source:
On the Home page, select the Sources secondary tab to display the Sources page.
For Source Type, select Web.
Click Create to display the Create Web Source page.
Complete the following fields:
Source Name: Name that you assign to this Web source.
Starting URLs : The HTTP or HTTPS address of the Web site, starting at the top page to be searched.
Self Service : Disabled to use an identity management system or Enabled to prompt users for their credentials.
Start Crawling Immediately : Select this option to accept the default parameters and begin crawling, or deselect it to defer crawling.
Click Create or Create & Customize.
Follow the steps for crawling and indexing a source in "Getting Started Basics for the Administration GUI".

Figure 5-2 Customizing a Web Source
When creating a Web source, the host name of the seed (top level URL) is automatically added to the boundary rule. However, subsequent changes to the seed URL are not reflected automatically to the rule. Remember to synchronize the boundary rule if there is any change to the seed URL. Currently, Oracle SES does not remove crawled URLs even if the original seed is removed: everything is controlled by the boundary rules.
Oracle SES crawls and indexes these Web document attributes:
Subject: Mapped to "Description". If there is no description metatag in the HTML file, then it is ignored.
Headline1: The highest H tag text; for example, "Annual Report" from
<H2>Annual Report</H2> when there is no H1 tag in the page.
Headline2: The second highest H tag text
Reference Text: The anchor text from another Web page that points to this page.
You can define additional HTML metatags to map to a String attribute on the Home - Sources - Metatag Mapping page.
