Peter, Instead of using NOT, try simply prefixing the field name with a minus sign. This tells SOLR to exclude the field. Otherwise, the word NOT would be treated as a term, and would be applied against your default field (which may or may not affect your results). So instead of (pubdate:[* TO NOW]) OR ( NOT pubdate:*), you would write (pubdate:[* TO NOW]) OR ( -pubdate:*). - Ken
