• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ґрунтова основеіііа\") OR (\"ґрунтова основеі\"))) OR (\"ґрунтова основ\"))".
• Removing quotes may allow a broader search: (((( ґрунтова основеіііа ) OR ( ґрунтова основеі ))) OR ( ґрунтова основ )).
• Adding a wildcard symbol may retrieve word variants: (((("ґрунтова основеіііа") OR ("ґрунтова основеі"))) OR ("ґрунтова основ"))*.
