• If you are trying to use Boolean operators, they must be ALL CAPS: (((("down teacher supply") OR ("down teacher support"))) OR ("can neither supply")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"down teacher supply\") OR (\"down teacher support\"))) or (\"can neither supply\"))".
• Removing quotes may allow a broader search: (((( down teacher supply ) OR ( down teacher support ))) or ( can neither supply )).
• Adding a wildcard symbol may retrieve word variants: (((("down teacher supply") OR ("down teacher support"))) or ("can neither supply"))*.
