Firebase高级词典搜索 [英] Firebase Advanced Dictionary Search

问题描述

我的Firebase中有许多电报键盘，而且我希望有一个高级字典搜索键盘的孩子，等级深，用户输入，

Forexample用户输入 rock ，我想让每个键盘包含在开始 end 或 end ，在这个例子中我有3个键盘： morning ， rock 和 rocky 。

  const ref = db.ref（'Keyboards / rock'）; //键盘1 
 const ref = db.ref（'Keyboards / morning'）; //键盘2 
 const ref = db.ref（'Keyboards / rocky'）; //键盘3 
  

我怎样才能取得和 console.log rock 时，c $ c>： rock 和 rocky >


我的问题90％由@rymdmaskin解决，但高级字典搜索仍然是打开的。

equalTo 和 startAt 和 endAt 不工作，我需要像包含使用弹性搜索（ https：// firebase .googleblog.com / 2014/01 / queries-part-2-advanced-searching-with.html ）
$ b 结构：



规则：

  {
rules：{
.read：true，
.write：true，
Keyboar ds：{
.indexOn：键盘
} 
} 
} 
  

代码：



  const ref = db.ref（ '/'）; （$）$ b $ ref.child（'/'）。orderByChild（'Keyboards'）。equalTo（'rock'）。on（value，function（snapshot）{
 console.log（snapshot.val ））; 
 key = snapshot.forEach（function（data）{
 console.log（data.key）; 
}）; 
}）; 
  




解决方案

Google目前做全文搜索的方法似乎是使用Algolia或BigQuery与云端功能同步Firebase。

使用（弹性搜索）：

I have many Telegram Keyboards in my Firebase, and I Want to Have an Advance Dictionery Search for Childs of Keyboards, I Mean in Secend Level Deep, that the user entered,
Forexample user entered rock, I want to get each Keyboards contain rock at the begin or middle or at the end, in This Example I have 3 Keyboards: morning, rock and rocky.

const ref = db.ref('Keyboards/rock');  //keyboard 1
const ref = db.ref('Keyboards/morning');  //keyboard 2
const ref = db.ref('Keyboards/rocky');  //keyboard 3

How Can I get and console.log: rock and rocky when user typed rock?
My Problem 90% Solved By @rymdmaskin But Advance Dictionery Search Still is Open.
equalTo and startAt and endAt Not Work, I need Something like contain, Someone Said to use Elastic Search (https://firebase.googleblog.com/2014/01/queries-part-2-advanced-searches-with.html)

Structure:

Rules:

{
  "rules": {
    ".read": true,
    ".write": true,
      "Keyboards" : {
             ".indexOn": "Keyboards"
         }
  }
}

Code:

const ref = db.ref('/');
  ref.child('/').orderByChild('Keyboards').equalTo('rock').on("value", function(snapshot) {
    console.log(snapshot.val());
    key = snapshot.forEach(function(data) {
        console.log(data.key);
    });
});

解决方案

Google's current method to do full text search seems to be syncing with either Algolia or BigQuery with Cloud Functions for Firebase.
