Perhaps you should try some spelling variations:
"optimates and populate" » "estimates and populate", "optimates and postulate", "optimates and popular", "optimates and modulate"
"Optimates and populares" » "Optimates and popular", "Optimates and popularly"
"Optimates and populated" » "Optimates and postulated", "Optimates and modulated", "Optimates and populard"

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: (((("Optimates and populares") OR ("Optimates and populated"))) OR ("optimates and populate"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"Optimates and populares\") OR (\"Optimates and populated\"))) or (\"optimates and populate\"))~".
• Removing quotes may allow a broader search: (((( Optimates and populares ) OR ( Optimates and populated ))) or ( optimates and populate ))~.
• Adding a wildcard symbol may retrieve word variants: (((("Optimates and populares") OR ("Optimates and populated"))) or ("optimates and populate"))*.
