• If you are trying to use Boolean operators, they must be ALL CAPS: sadhana (((((kier OR ier) OR ver) OR (hier OR her)) OR (((pier OR per) OR pie) OR piero)))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "sadhana (((((kier or ier) or ver) or (hier OR her)) or (((pier or per) or pie) or piero)))~".
• Adding a wildcard symbol may retrieve word variants: sadhana (((((kier or ier) or ver) or (hier OR her)) or (((pier or per) or pie) or piero)))*.
