Perhaps you should try some spelling variations:
"advances in chemistry studies" » "advances in chemistry study", "advances in chemical studies"
"advances in chemistry sources" » "advances in chemistry surfaces", "advances in chemistry force", "advances in chemistry some"
"advances in chemistry courses" » "advances in chemistry current"
"advances in chemistry series" » "advances in chemistry species", "advances in chemistry sars", "advances in chemistry seeing"
"advances in chemistry erich" » "advances in chemistry metrics", "advances in chemistry africa", "advances in 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 studies"))) OR ((("advances in chemistry sources") OR ("advances in chemistry courses")))).
• 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 studies\"))) or (((\"advances in chemistry sources\") OR (\"advances in chemistry courses\"))))".
• Removing quotes may allow a broader search: (((((( advances in chemistry series ) or ( advances in chemistry erich ))) or ( advances in chemistry studies ))) or ((( advances in chemistry sources ) OR ( advances in chemistry courses )))).
• Adding a wildcard symbol may retrieve word variants: (((((("advances in chemistry series") or ("advances in chemistry erich"))) or ("advances in chemistry studies"))) or ((("advances in chemistry sources") OR ("advances in chemistry courses"))))*.
