text: **15.6.4 Fuzzy and proximity searches**
  
  A fuzzy search query searches for character sequences that are not only the same but similar 
  to the query term. Use the tilde symbol (~) at the end of a term to perform a fuzzy search. For 
  example, the following query finds documents that include the terms analytics, analyze, and 
  analysis: 
  
  analytics~ 
  
  An optional parameter can be used to specify the required similarity. Specify a value greater 
  than 0 and less than 1. The value must be preceded by a 0 and decimal point, for example, 
  0.8: 
  
  analytics~0.8 
  
  A value closer to 1 matches terms with a higher similarity. If the parameter is not specified, the 
  default is 0.5. 
  
  A proximity search finds documents that contain terms within a specified number of words of 
  each other. Use the tilde symbol (~) to perform a proximity search. For example, the following 
  query finds documents that contain “IBM” and “WebSphere” within seven words of each 
  other: 
  
  "IBM WebSphere"~7 
  
  Proximity search is supported for individual terms, not phrases. Also, a word after a sentence 
  break is considered 10 positions apart from the last word of the previous sentence.
