Perhaps you should try some spelling variations:
"countries across barrier-sloop" » "countries cross barrier-sloop", "countries access barrier-sloop", "countries acronyms barrier-sloop", "countries across barriers-sloop", "countries access barriers-sloop", "countries across border-sloop"
"counter across brief-sloop" » "counter macros brief-sloop", "encounters across brief-sloop", "volunteer across brief-sloop", "counter across border-sloop", "counter across darien-sloop", "counter across build-sloop"
"counter across brush-sloop" » "counter macros brush-sloop", "encounters across brush-sloop", "volunteer across brush-sloop"
"counter across barrier-sloop" » "counter macros barrier-sloop", "encounters across barrier-sloop", "volunteer across barrier-sloop", "counter across barriers-sloop", "counter access barriers-sloop", "counter across border-sloop"

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 brush-sloop"))) OR ((("counter across barrier-sloop") OR ("countries across barrier-sloop")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"counter across brief-sloop\") OR (\"counter across brush-sloop\"))) or (((\"counter across barrier-sloop\") or (\"countries across barrier-sloop\"))))".
• Removing quotes may allow a broader search: (((( counter across brief-sloop ) OR ( counter across brush-sloop ))) or ((( counter across barrier-sloop ) or ( countries across barrier-sloop )))).
• Adding a wildcard symbol may retrieve word variants: (((("counter across brief-sloop") OR ("counter across brush-sloop"))) or ((("counter across barrier-sloop") or ("countries across barrier-sloop"))))*.
