• Performing a fuzzy search may retrieve terms with similar spellings: (((("ґрунтова основііе") OR ("ґрунтова основііеіные"))) OR ("ґрунтова основ"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ґрунтова основііе\") OR (\"ґрунтова основііеіные\"))) OR (\"ґрунтова основ\"))*".
• Removing quotes may allow a broader search: (((( ґрунтова основііе ) OR ( ґрунтова основііеіные ))) OR ( ґрунтова основ ))*.
