Perhaps you should try some spelling variations:
"optimates and populated" » "estimates and populated", "optimates and postulated", "optimates and modulated"
"optimates and popular" » "estimates and popular"
"Optimates and populate" » "Optimates and postulate"
"Optimates and modulate" » "Optimates and module", "Optimates and moderate", "Optimates and modular"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((((("Optimates and populate") OR ("Optimates and modulate"))) or ("optimates and populated"))) or ("optimates and popular"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("Optimates and populate") OR ("Optimates and modulate"))) OR ("optimates and populated"))) OR ("optimates and popular")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"Optimates and populate\") OR (\"Optimates and modulate\"))) or (\"optimates and populated\"))) or (\"optimates and popular\"))".
• Removing quotes may allow a broader search: (((((( Optimates and populate ) OR ( Optimates and modulate ))) or ( optimates and populated ))) or ( optimates and popular )).
• Adding a wildcard symbol may retrieve word variants: (((((("Optimates and populate") OR ("Optimates and modulate"))) or ("optimates and populated"))) or ("optimates and popular"))*.
