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