text: **15.6.1 Syntax**
  
  The FTS Server supports a rich query language that enables fuzzy searches, proximity 
  searches, weighted searches, and Boolean searches. 
  
  Queries can contain terms and operators. A*term*is a single word, such as “united”. A*phrase*
  is a group of words that are contained in quotation marks, such as “computer software”. 
  Phrases are searched as exact expressions. Stop words are not removed. No lemmatization 
  is performed. Boolean operators, such as AND, or wildcards, such as asterisk (*) or question 
  mark (?), are treated as literal characters. 
  
  Without quotation marks, the query is parsed and the syntactical options that are described in 
  the following sections are allowed. 
  
  **15.6.2 Boolean searches**
  
  Boolean operators allow terms to be combined through logical operators. The following 
  Boolean operators are supported: AND, OR, NOT, and the minus sign (-). 
  
  Boolean operators must be specified in all uppercase characters. For example, when you 
  search for documents about dogs or cats while you specify the OR Boolean operator, specify 
  the query as dogs OR cats, not dogs or cats. 
  
  Precede a term with a minus sign (-) to indicate that the term must be absent from a 
  document for a match to occur. For example, the following query returns documents that 
  include the term computer and not the term hardware: 
  
  computer -hardware
