• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"can research claire\") OR (\"can research claip\"))) or (\"canadian research claire\"))".
• Removing quotes may allow a broader search: (((( can research claire ) OR ( can research claip ))) or ( canadian research claire )).
• Adding a wildcard symbol may retrieve word variants: (((("can research claire") OR ("can research claip"))) or ("canadian research claire"))*.
