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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((((("head of state") OR ("head of late"))) OR ("had of state"))) OR ("meads of shape"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"head of state\") OR (\"head of late\"))) OR (\"had of state\"))) OR (\"meads of shape\"))".
• Removing quotes may allow a broader search: (((((( head of state ) OR ( head of late ))) OR ( had of state ))) OR ( meads of shape )).
• Adding a wildcard symbol may retrieve word variants: (((((("head of state") OR ("head of late"))) OR ("had of state"))) OR ("meads of shape"))*.
