Perhaps you should try some spelling variations:
"60th birth honours" » "60th its honours", "60th birth amours", "90th birth honours", "60 birth honours"
"60th birth occurs" » "60th birth amours", "60th death occurs", "90th birth occurs", "60 birth occurs"
"60th birthday honours" » "90th birthday honours", "60 birthday honours"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("60th birthday honours") OR ((("60th birth honours") OR ("60th birth occurs")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"60th birthday honours\") or (((\"60th birth honours\") OR (\"60th birth occurs\"))))".
• Removing quotes may allow a broader search: (( 60th birthday honours ) or ((( 60th birth honours ) OR ( 60th birth occurs )))).
• Adding a wildcard symbol may retrieve word variants: (("60th birthday honours") or ((("60th birth honours") OR ("60th birth occurs"))))*.
