Perhaps you should try some spelling variations:
"head of state" » "head or state", "head of hate", "head of shame", "had of state", "mead of state", "read of state"
"heads of late" » "means of late", "heads of hate", "heads of latin", "hads of late", "meads of late", "reads of late"
"years of late" » "means of late", "years of hate", "years of latin"
"lens of late" » "lens of hate", "lens of latin", "means 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 (((((\"heads of late\") OR (\"years of late\"))) OR (\"lens of late\"))))~".
• Removing quotes may allow a broader search: (( head of state ) OR ((((( heads of late ) OR ( years of late ))) OR ( lens of late ))))~.
• Adding a wildcard symbol may retrieve word variants: (("head of state") OR ((((("heads of late") OR ("years of late"))) OR ("lens of late"))))*.
