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