text: Before you can index a report with the OS/400 indexer, you must create a set of*indexing*
  *parameters*. The indexing parameters describe the physical characteristics of the input data, 
  identify where in the data stream the OS/400 indexer can locate index data, and provide other 
  directives to the OS/400 indexer. 
  
  Indexing parameters include information that allows the OS/400 indexer to identify key items 
  in the print data stream,*tag*these items, and create*index elements*that point to the tagged 
  items. The OS/400 indexer uses the tag and index data for efficient and structured search and 
  retrieval. You specify the index information that allows the OS/400 indexer to segment the 
  data stream into individual items called*groups*. A group is a collection of one or more pages. 
  You define the bounds of the collection, for example, a bank statement, insurance policy, 
  phone bill, or other logical segment of a report file. A group can also represent a specific 
  number of pages in a report. For example, you might decide to segment a 10,000 page report 
  into groups of 100 pages. The OS/400 indexer creates indexes for each group. Groups are 
  determined when the value of an index changes (for example, account number) or when the 
  maximum number of pages for a group is reached.
