<h2>Detailed Description</h2>
<p>\class OptionalTerm optionalterm.h Nepomuk/Query/OptionalTerm
</p>
<p>
Make a term optional.
</p>
<p>
%OptionalTerm can be used to mark another term as optional.
This is mostly useful with subterms of type ComparisonTerm
(or an AndTerm combining ComparisonTerms) which either have
additional bindings (ComparisonTerm.setVariableName()) or
a specified sort weight (ComparisonTerm.setSortWeight()).
