以上是我的项目要求的mongodb模态。现在我想要的是我必须搜索“标题”：“水果”只有水果名称应该来，结果我必须过滤公司“jessy transports”

我尝试的是

{"$text":{"$search":"jessy transports"}},{"array":{"$elemMatch":{"title":{"$in":[/Fruits/]}}}}

这里我使用了$ text搜索，因为我正在尝试搜索“Fruits”。我试图过滤“jessy transports”。但我得到了所有“jessy transports”，然后没有过滤“Fruits”

正是我想要的是当我搜索“水果”时我希望得到所有具有“标题”的水果：“水果”在阵列中。

- ＆GT;当我搜索“水果”时，我只想要公司名称有“jessy transports”，那么我必须得到有jessy运输的水果。

- ＆GT;当我搜索“水果”时，我只想要公司名称有“jessy transports”，结果我想要一个文本搜索“健康”

Answer 1

试试这个：

  db.YOUR_COLLECTION.aggregate(
    {$unwind:"$array"},
    {$match: {"array.title" :'fruits', 'company': 'jessy transports'}}).pretty()

使用$unwind然后匹配查询。它产生这样的结果

{
"_id" : ObjectId("58076939309f9df8e6b59573"),
"name" : "Apples",
"company" : "jessy transports",
"array" : {
    "title" : "Fruits"
},
"description" : "Fruits are good to health, vegitables are also good to health"
}
