Abstract
Describes the RANK command which enables searchers of DIALOG databases do statistical analysis online. Describes the basic features of the ranking command. The fields to which this command can be applied run into the thousands. Shows how RANK can be used for content analysis. Details the limitations of the command and compares it with the SORT command. Offers advice on ranking results without using this command
