                 [ searchOrExpr / searchAndExpr ]
 searchOrExpr  = RWS 'OR' RWS searchExpr

 searchWord    = 1*ALPHA ; Actually: any character from the Unicode categories L or Nl,
                                     but not the words AND, OR, and NOT
 

ATTENTION: This class does not support a percent-encoded searchPhrase because the URI parser's parseUri method percent decodes each query before calling parsers of query options.
