Perhaps you should try some spelling variations:
chemistry chemical » chemistry physical, chemistry technical
chemistry specific » chemistry specificity, chemistry species, chemistry specimen
chemistry special » chemistry social, chemistry section, chemistry space
chemistry series » chemistry species, chemistry studies, chemistry sources
chemistry erich » chemistry metrics, chemistry africa, chemistry ethics

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 (\"advances in chemistry erich\"))) or (\"advances in ((chemistry specific) OR (((chemistry special) OR (chemistry chemical))))\"))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((((\\"advances in chemistry series\\") or (\\"advances in chemistry erich\\"))) or (\\"advances in ((chemistry specific) or (((chemistry special) OR (chemistry chemical))))\\"))\"".
• Removing quotes may allow a broader search: (((( advances in chemistry series ) or ( advances in chemistry erich ))) or ( advances in ((chemistry specific) or (((chemistry special) OR (chemistry chemical)))) )).
