mongodb - Mogodb使用了文本索引，就不能使用复合索引？

Question

是不是如果使用了文本索引，就不能使用复合索引？
因为我用了下面的查询语句但是只做了文本索引：

db.tests.find({$text:{$search:'zhangshan'},'age':5,'city':'beijing'}

通过explain查看，他是做了text的索引。然后再从这个索引中去过滤出其他条件的！
那么我该怎么做才能全部走索引呢？
我想到把所有字段建立一个text索引。因为数据量大，所以没有尝试，想问问这个可行吗？
谢谢

补充一下explain()

Answer 1

试着回答一下：

1、首先想看看你的复合索引是具体怎么建立的？

2、执行的结果是按照选择的执行计划执行的；如果性能不满意，可以使用hint来指定您所创建的复合索引。
