Perhaps you should try some spelling variations:
nordic literature » gnostic literature, norse literature, erotic literature
heroic literature » erotic literature, epic literature, arabic literature
indic literature » indian literature, medica literature, music literature
vedic literature » medica literature, epic literature, medical literature

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: ((indic literature) OR (((((nordic literature) OR (vedic literature))) OR (heroic literature)))) (english) / fast*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((indic literature) or (((((nordic literature) OR (vedic literature))) or (heroic literature)))) (english) / fast*".
