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