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