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