你如何在mongo dart中搜索一系列文档？

Question

How do I search an array of documents in mongodb using the dart programming language?

Im using https://pub.dartlang.org/packages/mongo_dart for the driver

The example db collection looks like this

"name": [ {"full":"Tyler Thompson", "first":"Tyler", "last":"Thompson" } ]

Answer 1

Using the following query will help achieve your goal for the one name

String search = "Tyler";

{"name.full": {'\\$regex': '${search}'}

Hope that helps! Couldn't find an example, so I thought I'd give one!:)

Answer 2

You can try to look at https://github.com/vadimtsushko/mongo_dart/blob/master/example/queries.dart

It is plausible that for your sample something like this would work:

coll.find(where.eq('name.full','Tyler'))

or maybe

coll.find(where.match('name.full','^Tyl[eo]r'))
