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