If you don’t want to redirect users, but only make a particular search result the preferred response, you can use the document URL preference query rule with the following syntax:

docpref,weight,url,url,...

The weight argument is a positive integer between 1 and 100, and adjusts the relevancy computation to favor results that are from the document or documents listed in the URL arguments. The url arguments must be a reference to a valid index item (invalid URLs are ignored). If more than one url argument is provided, a Boolean OR of the document preferences is added. For example, the following action adds a document preference of 60 for results from one document:

docpref,60,http://www.mycorp.com/home.html
