• If you are trying to use Boolean operators, they must be ALL CAPS: (((dechet OR dechets) OR desert) OR (((deckert OR beckert) OR weichert) OR reichert)) liquid~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((dechet or dechets) or desert) or (((deckert OR beckert) or weichert) or reichert)) liquid~".
• Adding a wildcard symbol may retrieve word variants: (((dechet or dechets) or desert) or (((deckert OR beckert) or weichert) or reichert)) liquid*.
