• If you are trying to use Boolean operators, they must be ALL CAPS: (((( advances in chemistry species ) OR ( advances in chemistry studies ))) OR ( advances in ((chemistry specimen) OR (chemistry specific)) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( advances in chemistry species ) or ( advances in chemistry studies ))) or ( advances in ((chemistry specimen) OR (chemistry specific)) ))".
• Adding a wildcard symbol may retrieve word variants: (((( advances in chemistry species ) or ( advances in chemistry studies ))) or ( advances in ((chemistry specimen) OR (chemistry specific)) ))*.
