I'm trying to fetch documents which contain whatever I pass in url for filter which must present in title field or in tasks array of those documents:

example: localhost:4000/search?filter=Morning. here I'm looking for documents which contain Morning in their title or in their tasks.

But when I'm hitting the Api it is returning me all the documents.

This is my model

const mongoose = require("mongoose");
const schema = mongoose.Schema;

const title = new schema(
    {
       title:{ 
        type: String,
        trim: true
        }

    },
    {
        timestamps: true 
    }

    );

const task = new schema(
    {
    tasks:[{ type: String,trim: true}]
    },
    {
    timestamps: true 
    }
    )   

const toDoSchema = new schema({
    toDoTitle : title,
    toDoTasks: task

    },
    {
    timestamps: true 
    });

const toDoModel = mongoose.model("toDo", toDoSchema);
module.exports = toDoModel;

this is my controller for filtering:

//importing model
const toDoModel = require('../models/ToDoModel');

//importing utils function
const toDosPerPage = require("../utlis/ToDosPerPage")

const searchController = async (req,res)=>{

    try{
        const {filter} = req.query
        if(!filter) throw new Error("Please provide Something in filter to search");
        const filteredArray = await toDoModel.find({
            $or:[{title:new RegExp(filter,'i')},{tasks: new RegExp(filter,'i')}]
        });

        
        
        res.status(200).json({
            success: true,
            message: "Successfully fetched todos",
            filteredArray

        });

        }
        catch(err){
            res.status(401).json({
                success: false,
                message: "Some error occuried",
                error: err.message
            })
            console.log(err.message);
        } 
    }
    module.exports = searchController;

I want it to return only those documents which contain morning in their title or in their tasks fields.

CodePudding user response：

to find in embeded document use dot .

const filteredArray = await toDoModel.find({
   $or:[
        {'toDoTitle.title':new RegExp(filter,'i')},
        {'toDoTasks.tasks':new RegExp(filter,'i')}
   ]
});
