我想用 mongo-go-driver 创建一个动态过滤器。

例如，我有这些文件：

{
"_id":"5d1231380a2a2b39a99c3ed1"},
"name":"flower.png",
"colors":["#ffffff","#212121","#999999","#dbdbdb","#ff5252"],
},
{
"_id":"5d1231380a2a2b39a99c3ed0"},
"name":"image of go.jpg",
"colors":["#dedede","#dfdfdf","#dddddd","#e0e0e0","#e2e2e2"],
},
{
"_id":"5d1231380a2a2b39a99c3ecf"},
"name":"bolket rulez.png",
"colors":["#000000","#010101","#020202","#030303","#040404"],
},
{
"_id":"5d1231380a2a2b39a99c3ecf"},
"name":"bolket photo.png",
"colors":["#ffffff","#010101","#020202","#030303","#040404"],
}

现在我想要所有名称中带有“bolket”和“#ffffff”颜色的文档。

我试过这个过滤器：

filter := make(bson.D, 2)

    if f.Name != "" {
        filter = append(filter, bson.E{Key: "name", Value: bson.M{"$text": bson.M{"$search": f.Name}}})
    }

    if f.Color != "" {
        filter = append(filter, bson.E{Key: "colors", Value: bson.M{"$in": f.Color}})
    }

但是使用这个过滤器我有这个错误：(BadValue) unknown operator: $text

如何创建动态过滤器？？？

跨文档上的文本索引字段查询操作$text搜索，您不能使用单字段搜索$text

假设您已经在 上创建了文本索引name，然后尝试：

  if f.Name != "" {
        filter = append(filter, bson.E{Key: "$text", Value: bson.M{"$search": f.Name}})
    }
