Perhaps you should try some spelling variations:
"sub specic aeternitatis" » "sub specific aeternitatis", "sub specc aeternitatis", "sub speckc aeternitatis"
"sub specice aeternitatis" » "sub specifice aeternitatis", "sub specimen aeternitatis", "sub specce aeternitatis", "sub speckce aeternitatis"
"sub speci aeternitatis" » "sub spec aeternitatis", "sub speck 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 specic aeternitatis") OR ("sub specice aeternitatis"))) OR ("sub speci aeternitatis"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"sub specic aeternitatis\") OR (\"sub specice aeternitatis\"))) OR (\"sub speci aeternitatis\"))".
• Removing quotes may allow a broader search: (((( sub specic aeternitatis ) OR ( sub specice aeternitatis ))) OR ( sub speci aeternitatis )).
• Adding a wildcard symbol may retrieve word variants: (((("sub specic aeternitatis") OR ("sub specice aeternitatis"))) OR ("sub speci aeternitatis"))*.
