How to create queries in the free text search:

  • Add double quotes around a group of words to search for pages containing that group (e.g. "fuel cells")
  • AND (or &&):  wind AND "solar panels" returns pages containing both "wind" and "solar panels".
  • OR (or a space): wind "solar panels" returns pages containing wind or "solar panels".
  • NOT (or !): solar NOT "solar panels" returns pages containing solar but not "solar panels".
  • Use the various filters (left column) to refine or reset your search.
