Perhaps you should try some spelling variations:
present challenges » current challenges, assessment challenges
3 present » _ present
yang jui » yang judy, yang di, yang yi
yang xi » yang di, yang yi
dans la » dans les
1 dans » l1 dans, 4 dans, e dans
new a » new _, now a, new 4
wang » wing, wan

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((wang or lang) yan) or (((yang jui) or (yang xi))))new a 3 present challenges 1 dans la ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((wang OR lang) yan) OR (((yang jui) OR (yang xi))))new a 3 present challenges 1 dans la ;.
• Adding a wildcard symbol may retrieve word variants: (((wang or lang) yan) or (((yang jui) or (yang xi))))new a 3 present challenges 1 dans la ;*.
