<li ng-repeat="phone in phones|filter:query">

一般都是这样写过滤，但是我想只针对一部分数据，phone.name实现过滤这个要如何实现呢？？

根据官方文档的描述，有几种方式来实现：
{{ filter_expression | filter : expression : comparator}}

1.如Guox给出的方法,使用expression:

Object: A pattern object can be used to filter specific properties on objects contained by array. For example {name:"M", phone:"1"} predicate will return an array of items which have property name containing "M" and property phone containing "1".

作为Object使用，用于过滤数组元素的指定属性，如expression = {name:"M", phone:"1"} ，那么将会过滤出数组中name包含'M'且phone包含'1'的元素。

故使用如下方法即可

<li ng-repeat="phone in phones|filter:{name:query}">

2.可以使用comparator：

Comparator which is used in determining if the expected value (from the filter expression) and actual value (from the object in the array) should be considered a match.
function(actual, expected): The function will be given the object value and the predicate value to compare and should return true if both values should be considered equal.

通过Comparator的返回值能够决定是否匹配，入参分别是actual（数组中的元素）和expected（输入）

那么定义一个函数

$scope.customerFilter = customerFilter;

function customerFilter(actual, expected){
    return actual.name.contains(expexted) ? true : false;
}

前端使用
<li ng-repeat="phone in phones|filter:query:customerFilter">
