• If you are trying to use Boolean operators, they must be ALL CAPS: (("own water supply") OR ((("town water supply") OR ("down water supply")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"own water supply\") or (((\"town water supply\") OR (\"down water supply\"))))".
• Removing quotes may allow a broader search: (( own water supply ) or ((( town water supply ) OR ( down water supply )))).
• Adding a wildcard symbol may retrieve word variants: (("own water supply") or ((("town water supply") OR ("down water supply"))))*.
