Perhaps you should try some spelling variations:
chemistry specimen » chemistry special, chemistry specific, chemistry experiment
chemistry sediment » chemistry experiment, chemistry experiments, chemistry department
chemistry metrics » chemistry methods, chemistry optics, chemistry materials
chemistry species » chemistry special, chemistry spaces, chemistry specific
chemistry series » chemistry studies, chemistry sources, chemistry erich
chemistry sars » chemistry sets, chemistry spps, chemistry sr

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: "((((\"advances in ((chemistry series) OR (chemistry sars))\") or (\"advances in chemistry metrics\"))) or (\"advances in ((chemistry species) OR (((chemistry specimen) OR (chemistry sediment))))\"))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((((\\"advances in ((chemistry series) or (chemistry sars))\\") or (\\"advances in chemistry metrics\\"))) or (\\"advances in ((chemistry species) or (((chemistry specimen) OR (chemistry sediment))))\\"))\"".
• Removing quotes may allow a broader search: (((( advances in ((chemistry series) or (chemistry sars)) ) or ( advances in chemistry metrics ))) or ( advances in ((chemistry species) or (((chemistry specimen) OR (chemistry sediment)))) )).
