+ <para>
+ Ignore unknown Spotlight attributes in search queries. An example query
+ using the unsupported attribute
+ <literal>"kMDItemTopic"</literal> would be
+ <literal>kMDItemTopic=="hotstuff"</literal>. By
+ default any query using such a type would completely fail. By enabling
+ this option, if the type match is a subexpression of a larger expression,
+ then this subexpression is just ignored.
