Perhaps you should try some spelling variations:
"acta slavica estonian" » "acta latvia estonia", "acta place estonian", "art slavic estonian", "et slavica estonian"
"anna slavina estonian" » "anna slovenia estonia", "anna latvia estonia", "anna golovina estonian", "anna karina estonian", "anna lina estonian"
"anna latvian estonian" » "anna latvia estonia", "anna latvian social", "suna latvian estonian", "among latvian estonian", "anna livia estonian"

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 ("anna latvian estonian")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"acta slavica estonian\") or (((\"anna slavina estonian\") OR (\"anna latvian estonian\"))))".
• Removing quotes may allow a broader search: (( acta slavica estonian ) or ((( anna slavina estonian ) OR ( anna latvian estonian )))).
• Adding a wildcard symbol may retrieve word variants: (("acta slavica estonian") or ((("anna slavina estonian") OR ("anna latvian estonian"))))*.
