Perhaps you should try some spelling variations:
chemical specificity » biochemical specificity, chemical specific, chiral specificity
chemistry species » chemistry specimen, chemistry special, chemistry spaces
chemistry series » chemistry studies, chemistry sources, chemistry erich

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 species) OR (chemistry series))\") or (\"advances in chemical specificity\"))".
• Removing quotes may allow a broader search: (( advances in ((chemistry species) or (chemistry series)) ) or ( advances in chemical specificity )).
