Perhaps you should try some spelling variations:
"sub specie aeternitatis" » "sub species aeternitatis", "sub specic aeternitatis", "sub specimen aeternitatis", "sub specice aeternitatis", "sub specke aeternitatis", "sub speckie aeternitatis", "sub speie aeternitatis", "sub pecie aeternitatis"
"sub speci aeternitatis" » "sub specic aeternitatis", "sub speck aeternitatis", "sub specki aeternitatis", "sub spei aeternitatis", "sub peci aeternitatis"
"sub specki aeternitatis" » "sub speck aeternitatis", "sub speckki aeternitatis", "sub speki aeternitatis", "sub pecki aeternitatis"
"sub spec aeternitatis" » "sub speck aeternitatis", "sub spe aeternitatis", "sub pec aeternitatis"

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

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