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