Abstract
Technologies are described herein for providing a more efficient approach to ranking search results. One method reduces an amount of ranking data analyzed at query time. In the method, a term is selected, at index time, from a master index. The term corresponds to a number of documents greater than a threshold. A set of documents that includes the term is selected based on the master index. A rank is determined for each document in the set of documents that contains the term. Each document in the set of documents that contains the term is assigned to a high ranking index or a low ranking index based on the simple rank.
