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