Change the default rank profile by using the graphical interface

When a user types one or more search words into the Search Box Web Part on the search page (default.aspx) in the Search Center site, the search service returns the results displayed in various Web Parts on the search results page (results.aspx). If the search words did not contain any keywords or associated synonyms, the order of the search results are based on the rank score calculated by the default rank profile. The label of the default rank profile is displayed in the Sort by pull down menu. The default search results page uses the default rank profile, which is labeled Relevance in the Sort by pull down menu. Use the following procedure to change the default rank profile via the graphical interface:

1. On the Search Center site, enter a search word and then click the Search icon.

2. On the Search results page, click the Site Actions menu, and then click Edit Page.

3. From the Search Action Links Web Part Menu select Edit Web Part.

4. In the web part tool pane, expand Display Properties to display all existing rank profiles.

5. Select the rank profile that you want to set as default by clicking the Default radio button and checking the Enabled check box next to it.

6. Click OK.

7. Click Save & Close.

The new default rank profile will now appear in the Sort by pull down menu.
