The classes themselves do not require a query term. They just require a field name. my $null_query = LucyX::Search::NullTermQuery->new( field => 'foo' ); Or are you asking if the query parser supports this syntax: foo: instead of: foo:NULL I.e., the empty string and the undef value are considered equivalent to NULL. > Also, is there a > way to query multiple fields? > sure. join them with OR or AND. foo:NULL or bar:NULL -- Peter Karman . http://peknet.com/ .
