mongodb和/或combo [英] mongodb and or combo

问题描述

我如何在mongodb中执行此操作....

How do i do this in mongodb....

(a || b || c) || (d && e)

推荐答案

(a || b || c)|| (d& e)等于(a || b || c ||(d& e))

(a || b || c) || (d && e) is equivalent to (a || b || c || (d && e))

如果abcde是您的字段，而12345是值(简单的情况下，您可以输入那些表达式):

if abcde are your fields and 12345 are the values (simple case you can put whatever as those expressions):

 db.foo.find( { $or : [ { a : 1 } , { b : 2 },{ c : 3 },{ d : 4 , e :5} ] } );

请注意，这是针对mongodb> = 1.5.3的较早版本，没有$ or

Note this is for mongodb >= 1.5.3 earlier ones do not have $or
