• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"ґрунтова ((основеііа\\" OR основні\\") OR (основеа\\" OR основніа\\"))) OR (\\"ґрунтова основ\\"))~\"".
• Removing quotes may allow a broader search: (( ґрунтова ((основеііа OR основні ) OR (основеа OR основніа ))) OR ( ґрунтова основ ))~.
