Perhaps you should try some spelling variations:
"n.t latvian estonian" » "n.t latvia estonia", "n.t latvian social", "toth latvian estonian"
"acta slovenia estonia" » "malta slovenia estonia", "area slovenia estonia", "art slovenia estonia"
"n.t latin estonia" » "n.t latvia estonia", "n.t talinn estonia", "n.t tallin estonia"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("acta slovenia estonia") OR ((("n.t latin estonia") OR ("n.t latvian estonian")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"acta slovenia estonia\") or (((\"n.t latin estonia\") OR (\"n.t latvian estonian\"))))".
• Removing quotes may allow a broader search: (( acta slovenia estonia ) or ((( n.t latin estonia ) OR ( n.t latvian estonian )))).
• Adding a wildcard symbol may retrieve word variants: (("acta slovenia estonia") or ((("n.t latin estonia") OR ("n.t latvian estonian"))))*.
