#521: Precedence of HATE is surprising

 This query:

 {{{a OR b -c}}}

 gets parsed as:

 {{{a OR (b -c}}}

 rather than the more obvious interpretation of:

 {{{(a OR b) -c}}}

 While this appears to be just a precedence issue, actually NOT is resolved
 within a "term group" and {{{b -c}}} is a term group here, so this might
 take a bit of reworking to fix.
