Comment:

 Under: FLAG_BOOLEAN | FLAG_PARTIAL | FLAG_AUTO_SYNONYMS

 {{{
 // PROBLEM - EXPLICIT "~" SHOULD FORCE LOOK FOR A SYNONYM
 // Xapian::Query(hello:(pos=1))
 $query = $qp->parse_query('~hello', $xapianFlags);
 }}}

 I'm not sure I agree here.  You didn't pass FLAG_SYNONYM, so the "~"
 synonym operator isn't enabled, and the "~" is ignored as a spurious
 character (like "%" would be in "%hello", for example).  So this case is
 handled just as {{{'hello'}}} is.

 If you want "~" to be recognised as meaning "synonym this explicitly", I
 think you should be passing FLAG_SYNONYM.  FLAG_AUTO_SYNONYMS could imply
 FLAG_SYNONYM, but then we lose the flexibility of not having "~"
 recognised specially.

 Similar arguments apply to: {{{world ~hello}}}

 The other cases are fixed in trunk r13611.

 Marking for backport to 1.1.17.
