Perhaps you should try some spelling variations:
"acta slavica estonian" » "acta place estonian", "art slavic estonian", "et slavica estonian"
"anna slavina estonian" » "anna slovenia estonia", "anna golovina estonian", "anna karina estonian", "anna lina estonian"
"acta latvian estonian" » "acta latvian social", "suna latvian estonian", "toth latvian estonian"
"toth latvia estonia" » "toth latvian estonia", "youth latvia 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 slavica estonian") OR ("anna slavina estonian"))) OR ((("acta latvian estonian") OR ("toth latvia estonia")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"acta slavica estonian\") OR (\"anna slavina estonian\"))) or (((\"acta latvian estonian\") or (\"toth latvia estonia\"))))".
• Removing quotes may allow a broader search: (((( acta slavica estonian ) OR ( anna slavina estonian ))) or ((( acta latvian estonian ) or ( toth latvia estonia )))).
• Adding a wildcard symbol may retrieve word variants: (((("acta slavica estonian") OR ("anna slavina estonian"))) or ((("acta latvian estonian") or ("toth latvia estonia"))))*.
