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

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