   Memo Fields

   Clipper's memo fields are intended to provide an easy and flexible 
   method for storing large amounts of free-form text. While Clipper 
   supplies many useful functions for managing memo fields, it does not 
   provide any simple or fast mechanism to search their contents. This 
   weakness limits the full potential of memo fields by making the job of 
   finding words and phrases stored in memo fields difficult and slow. 
   
   Use CFTS to plug this gap in Clipper's search tools by treating the 
   contents of a memo field as just another string of text, no different 
   from that stored in any other character field. We use this technique 
   in the BIB.PRG demo program; we even take it one step further and treat
   the contents of all fields, including a memo field, as one long 
   string. Keep in mind that CFTS works best with strings less than 4000 
   characters long. With strings of this size, we recommend you use the 
   largest SIZE FACTOR (3 ) when creating the original CFTS index. See 
   the sections discussing CftsCrea().
