text: **Important:**Size the box that you created around the text string, which you are trying 
  to collect, as large as possible to ensure that the field is collected at load time. 
  
  Figure 7-3 on page 171 shows an example of a box that is intended to capture the text 
  string Content. You can see that the box is much larger than the text string, and it 
  overlaps onto text that we do not want to collect. However, notice the Add a Trigger box 
  that is displayed; only the string Content is shown in the Value entry field, which means 
  that only the string Content is*fully*encapsulated in the box. Overlapping other text 
  might seem like an unnecessary precaution. However, when we are capturing data with 
  the PDF graphical indexer, it is an excellent way to ensure that we encapsulated*all*of 
  the text string that we must capture.
