Perhaps you should try some spelling variations:
"atlantic context" » "atlantic continental"
"semantic context" » "semantic content", "semantic concepts", "semantic text"
"atlantic coast" » "atlantic cost"

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: (((("atlantic context") OR ("atlantic coast"))) OR ("semantic context")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"atlantic context\") OR (\"atlantic coast\"))) or (\"semantic context\"))".
• Removing quotes may allow a broader search: (((( atlantic context ) OR ( atlantic coast ))) or ( semantic context )).
• Adding a wildcard symbol may retrieve word variants: (((("atlantic context") OR ("atlantic coast"))) or ("semantic context"))*.
