• The words AND, OR and NOT may confuse the search; try adding quotes: "\"\\"((\\\"ґрунтова ((основііа\\\" OR основеііііііа\\\") OR основеі\\\")) OR (\\\"ґрунтова основ\\\"))*\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова ((основііа\ OR основеііііііа\ ) OR основеі\ )) OR (\ ґрунтова основ\ ))*.
