text: **15.6.5 Weighted searches (boosting terms)**
  
  Follow a search term by a boost value to influence how documents that contain a specified 
  term are ranked in the search results. Use the caret symbol (^) with a number (the boost 
  factor) at the end of the term. For example, the following query finds documents that include 
  the terms IBM and Germany and increases the relevance of these documents by a factor of 
  five in the search results: 
  
  ibm Germany^5.0
