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

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