Search results
The I²plus results are sorted by a relevance score. The relevance of a page is determined by two values: the frequency of search terms in the title or in the text and the rank of the site where the retrieved page is located. The I²plus order of hits is determined by a combination of these two factors.
Fifteen results per page are shown as default display. You have the option to choose how many results you wish to display per page, by using the appropriate box.
