+The current query language is a bit awkward, but functional:
+
+query    ::= complex | simple | attr query.
+complex  ::= operator query query.
+operator ::= '@and' | '@or' | '@not'.
+simple   ::= term | set.
+term     ::= <word> | '"' <term> ... '"'.
+set      ::= '@set' <setname>.
+attr     ::= '@attr' <number> '=' <number>.

+"Hans Andersen"
