Perhaps you should try some spelling variations:
counter across » counter macros, encounters across, countries across
across darien » across barrier, across patient, across arid
across brief » across barrier, across border, across brush
counter mac » counter a, unter mac, counter act
mac built » mac build, jack built, a built

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: (((( counter across brief-sloop ) OR ( counter across darien-sloop ))) OR ( counter mac built-sloop )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( counter across brief-sloop ) OR ( counter across darien-sloop ))) or ( counter mac built-sloop ))".
• Adding a wildcard symbol may retrieve word variants: (((( counter across brief-sloop ) OR ( counter across darien-sloop ))) or ( counter mac built-sloop ))*.
