Perhaps you should try some spelling variations:
"advanced in chemistry special" » "advanced in chemistry social", "advanced in chemistry chemical", "advanced in chemistry section"
"advanced in chemistry snakes" » "advanced in chemistry spaces", "advanced in chemistry state", "advanced in chemistry sars"
"advanced in chemistry space" » "advanced in chemistry some", "advanced in chemistry simple"

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: (((("advanced in chemistry snakes") OR ("advanced in chemistry space"))) OR ("advanced in chemistry special")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"advanced in chemistry snakes\") OR (\"advanced in chemistry space\"))) or (\"advanced in chemistry special\"))".
• Removing quotes may allow a broader search: (((( advanced in chemistry snakes ) OR ( advanced in chemistry space ))) or ( advanced in chemistry special )).
• Adding a wildcard symbol may retrieve word variants: (((("advanced in chemistry snakes") OR ("advanced in chemistry space"))) or ("advanced in chemistry special"))*.
