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