Perhaps you should try some spelling variations:
"lexical resources" » "digital resources"
"coastal resources" » "digital resources", "local resources"
"social resources" » "local resources", "digital resources"

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: (((("social resources") OR ("coastal resources"))) OR ("lexical resources")).
• Removing quotes may allow a broader search: (((( social resources ) or ( coastal resources ))) or ( lexical resources )).
• Adding a wildcard symbol may retrieve word variants: (((("social resources") or ("coastal resources"))) or ("lexical resources"))*.
