Question

我有類似的表如下：

Name city state country 
---- ---- ----- ------- 
Sree mm  ap  ind 
SRee redmond ny  us 
rahul hyd  ap  ind 
xxx  mm  ap  ind 
abcd mm  tn  ind 
wer  dd  ap  ind 

如果我mm,ap尋找我需要得到這些。

Name city state country 
---- ---- ----- ------- 
Sree mm  ap  ind 
xxx  mm  ap  ind 
abcd mm  tn  ind 
wer  dd  ap  ind 

如果這兩個詞相匹配，應該是第一位的，如果包含city秒州和第三作爲國家。

請幫我這個。
