Perhaps you should try some spelling variations:
"head of state" » "head or state", "head of shame", "had of state", "mead of state", "read of state"
"meads of state" » "meads or state", "meads of shame", "means of state", "years of state"
"meads of hate" » "means of hate", "years of hate", "meads of shame"
"heads of late" » "means of late", "years of late", "heads of latin", "hads of late", "meads of late", "reads of late"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"head of state\") OR (((((\"meads of state\") OR (\"meads of hate\"))) OR (\"heads of late\"))))~".
• Removing quotes may allow a broader search: (( head of state ) OR ((((( meads of state ) OR ( meads of hate ))) OR ( heads of late ))))~.
• Adding a wildcard symbol may retrieve word variants: (("head of state") OR ((((("meads of state") OR ("meads of hate"))) OR ("heads of late"))))*.
