Perhaps you should try some spelling variations:
chemistry specific » chemistry specificity, chemistry species, chemistry specimen
chemistry metrics » chemistry methods, chemistry optics, chemistry materials
chemistry special » chemistry social, chemistry chemical, chemistry section
chemistry series » chemistry species, chemistry studies, chemistry sources
chemistry erich » chemistry africa, chemistry ethics, chemistry eco

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