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