• The words AND, OR and NOT may confuse the search; try adding quotes: "fop ((petruv OR (((petrv OR petriv) OR petra) OR petru)) OR (peteriu OR (peteri OR peterdi))) o.s.~".
• Adding a wildcard symbol may retrieve word variants: fop ((petruv OR (((petrv OR petriv) OR petra) OR petru)) OR (peteriu OR (peteri OR peterdi))) o.s.*.
