• If you are trying to use Boolean operators, they must be ALL CAPS: anejo del (bones OR bone) (((viii OR xxii) OR ((xxxiiii OR (xxviii OR xxxiiii)) OR iii)) OR xvii)~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "anejo del (bones OR bone) (((viii or xxii) or ((xxxiiii or (xxviii or xxxiiii)) or iii)) or xvii)~".
• Adding a wildcard symbol may retrieve word variants: anejo del (bones OR bone) (((viii or xxii) or ((xxxiiii or (xxviii or xxxiiii)) or iii)) or xvii)*.
