Add a site hit frequency rule to modify demands on specific sites as they are crawled. For more information about site hit frequency rules, see About Site Hit Frequency Rules.

Add a site hit frequency rule

1. On the SharePoint Portal Server Central Administration for Server server_name page, in the Component Configuration section, click Manage the Search Service.
2. On the Manage the Search Service for SharePoint Portal Server page, in the Site Hit Frequency Rules section, click Manage site hit frequency rules.
3. On the Site Hit Frequency Rules page, click Add Update Rule.
4. On the New Site Hit Frequency Rule page, in the Name section, in the Site name box, type the site name.

   A site name should be in the following form: example.microsoft.com. Do not include http:// in front of the site name.

   You can specify rules for individual sites. You can also use wildcard characters in site names to specify rules for multiple sites, as shown in the following table.

   Use	To
   * as the site name	Apply the rule to all sites.
   *.* as the site name	Apply the rule to sites with dots in the name.
   *.site_name.com as the site name	Apply the rule to all sites in the site_name.com domain (for example, *.adventure-works.com).
   *.top-level_domain_name (such as *.com or *.net) as the site name	Apply the rule to all sites that end with a specific top-level_domain_name (for example, .com, .net).
   ?	Replace a single character in a rule. For example, *.adventure-works?.com would apply to all sites in the domains adventure-works1.com, adventure-works2.com, etc.

   You can create a frequency rule for *.com that applies to all Internet sites that end in .com. For example, an administrator of a portal might add a content source for samples.microsoft.com. The rule for *.com would apply to this site unless you add a frequency rule specifically for samples.microsoft.com.

5. In the Request Frequency section, select one of the following frequency options:
   • Request documents simultaneously  Microsoft Office SharePoint Portal Server 2003 uses all allocated system resources to request as many documents as possible, with no delay between document requests. This setting is usually too resource-intensive for Internet sites but can be acceptable for intranet sites.
   • Limit the number of simultaneous document requests  You can specify the maximum number of documents that SharePoint Portal Server can request at one time from the site.

     In the Number of documents box, type the number of documents to request. The default setting for all sites is five simultaneous document requests.

     The minimum number of documents that SharePoint Portal Server can request is one. The maximum number of documents that SharePoint Portal Server can request is 999.

   • Wait a specified amount of time after each document request  You can specify a delay between document requests. SharePoint Portal Server requests one document per site at one time, and then waits for the specified amount of time before making additional requests.

     In the Time to wait in seconds box, type the time to wait between document requests.

     The minimum time to wait between document requests is one second. The maximum time to wait between document requests is 999 seconds.

   If the frequency is too high, SharePoint Portal Server can overload some Web sites with requests. Consider specifying lower frequency rates for Internet sites over which you have no control and higher frequency rates for intranet sites over which you do have control.
