• If you are trying to use Boolean operators, they must be ALL CAPS: (((("specialized periodicals reports") OR ((("socialism periodicals reports") OR ("socialism periodical returns"))))) OR ("specialist period returns")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"specialized periodicals reports\") or (((\"socialism periodicals reports\") OR (\"socialism periodical returns\"))))) or (\"specialist period returns\"))".
• Removing quotes may allow a broader search: (((( specialized periodicals reports ) or ((( socialism periodicals reports ) OR ( socialism periodical returns ))))) or ( specialist period returns )).
• Adding a wildcard symbol may retrieve word variants: (((("specialized periodicals reports") or ((("socialism periodicals reports") OR ("socialism periodical returns"))))) or ("specialist period returns"))*.
