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