Perhaps you should try some spelling variations:
"across countries, michigan" » "cross country, michigan", "across cultures, michigan"
"across country, michigan" » "cross country, michigan", "cross county, michigan", "acronyms country, michigan"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"across country, michigan\") OR (\"across countries, michigan\"))".
• Removing quotes may allow a broader search: (( across country, michigan ) OR ( across countries, michigan )).
• Adding a wildcard symbol may retrieve word variants: (("across country, michigan") OR ("across countries, michigan"))*.
