Perhaps you should try some spelling variations:
islamic renewal » islamic revival
2f egypt » _ egypt, 1 egypt, 6 egypt
99 cairo » a cairo
2 egypt » _ egypt, 1 egypt, 6 egypt
f case » 8 case

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: %((22islamic renewal) OR (islamic renewal)) %((2f egypt) OR (2 egypt)) %((99 cairo) OR (((gr cairo) OR (_ cairo)))) %((f case) OR (20 case)) studies%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((22islamic renewal) or (islamic renewal)) %((2f egypt) OR (2 egypt)) %((99 cairo) or (((gr cairo) or (_ cairo)))) %((f case) or (20 case)) studies%22".
• Adding a wildcard symbol may retrieve word variants: %((22islamic renewal) or (islamic renewal)) %((2f egypt) OR (2 egypt)) %((99 cairo) or (((gr cairo) or (_ cairo)))) %((f case) or (20 case)) studies%22*.
