• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"mars colonization israel\") OR (\"its colonization failed\"))) OR (\"its cooperation history\"))*".
• Removing quotes may allow a broader search: (((( mars colonization israel ) OR ( its colonization failed ))) OR ( its cooperation history ))*.
