Perhaps you should try some spelling variations:
"90th birthday honours" » "70th birthday honours", "80th birthday honours", "65th birthday honours"
"60th birth honours" » "60th its honours", "60th birth amours", "60th birth occurs", "90th birth honours", "60 birth honours"
"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 ("90th birthday honours"))) OR ("60th birth honours")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"60th birthday honours\") OR (\"90th birthday honours\"))) or (\"60th birth honours\"))".
• Removing quotes may allow a broader search: (((( 60th birthday honours ) OR ( 90th birthday honours ))) or ( 60th birth honours )).
• Adding a wildcard symbol may retrieve word variants: (((("60th birthday honours") OR ("90th birthday honours"))) or ("60th birth honours"))*.
