text: **7.4.2 The index file**
  
  ACIF creates the index file. It contains the index values that are extracted from the document, 
  and also the offsets and lengths of the documents in the .out file. 
  
  The index values in the index file become the values that display in the Content Manager 
  OnDemand Search Results window. The indexes are used to retrieve the document, which is 
  why the index file is so important, and why no data can be loaded without indexes. Usually, 
  the index file is created and used to load the documents into Content Manager OnDemand 
  and you never see it. However, it might be useful to look at the index file. This section 
  describes the format and content of the index file.

  the file consists of the two AFP Structured Fields: Index Element (IEL) and Tag Logical 
  Element (TLE). Two kinds of IELs exist: Page Group and Page. The index file must contain 
  Page Group IELs for**arsload**to load the data.
