Perhaps you should try some spelling variations:
"head of latin" » "head in latin", "had of latin", "lead of latin", "ead of latin"
"mead of state" » "mead or state", "mead of hate", "mead of shame", "means of state"
"heads of state" » "heads or state", "heads of hate", "heads of shame", "means of state", "years of state", "hads of state", "leads of state", "eads of state"
"read of late" » "triad of late", "read of hate"

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: "((((((\"read of late\") OR (\"head of latin\"))) OR (\"mead of state\"))) OR (\"heads of state\"))~".
• Removing quotes may allow a broader search: (((((( read of late ) OR ( head of latin ))) OR ( mead of state ))) OR ( heads of state ))~.
• Adding a wildcard symbol may retrieve word variants: (((((("read of late") OR ("head of latin"))) OR ("mead of state"))) OR ("heads of state"))*.
