[英]Filter on mongoDb an array of strings
我正在构建一个聊天机器人,我想用用户的输入过滤一个 MongoDb 数据库
words=["hello","price","bye"]
{
"Lang": "en",
"kw1": [
"price"
],
"Keyword Group 2": [
"test"
],
"Keyword Group 3": [
"res"
],
"Type": "Text",
"Text": "aaaaaAAAAAaaa",
"createdAt": 1662724328993,
"etag": "d-Zwyn11c6q6DfK+AV6RVxl9i7OJQ",
"_version": 2,
"updatedAt": 1662724336488
}
我试过这样做
this.fetchDataFromDataSource({ channel: this.channel, collectionName: "62a985781cd96396e4e1cba3_test", filter:{ kw1: words
} }).then((result) => {
console.log(result)
})
当输入只是一个单词时,它运行良好,但是当我发送多个单词时,它的行为不符合预期,我应该怎么做?
尝试使用$in
运算符:
this.fetchDataFromDataSource({
channel: this.channel,
collectionName: '62a985781cd96396e4e1cba3_test',
filter: { kw1: { $in: words } },
}).then((result) => {
console.log(result);
});
