Mongoose partial text search with sorting by revelance

I'm trying to query my mongodb database via mongoose, sorting the most relevant items first.
The following code works, but only returns results that contain the search parameter as a full word.
E.g. example will return items that include fields such as, ⁣ but{name: "example-item", description: "this is an example description"} but examp won't return that same item. I'd also like for it to search across multiple fields, as my current code does.
I'm aware you can do this partial search using regex but then you're not able to sort by textScore. Is there any way to do both? Sorting after each request is not possible as it will be paginated and handling somewhat large data.
let searchValue = "examp";
let matchingItems = await Items.find(
{
$text: {
$search: searchValue,
}
},
{
score: {
$meta: "textScore"
}
},
{
sort: {
score: {
$meta: "textScore"
}
}
}
);
Example DB data:
[
{name: "dignissim", description: "Lorem ipsum dolor sit amet, consectetur adipiscing elit."},
{name: "Fusce eget.", description: "Nullam malesuada ex sit amet diam ultrices"},
{name: "Duis nec", description: "Proin at dolor at est porta aliquet. Proin viverra imperdiet orci, a ornare tortor"},
{name: "Mauris.", description: "Aenean tristique ante et eros porttitor, ut sodales ipsum pulvinar."},
{name: "Pellentesque", description: "Nam dignissim ipsum a elit fermentum"},
{name: "facilisis augue", description: "Etiam sit amet dolor sed sapien rutrum sodales."},
{name: "erat suscipit", description: "this is an example description"},
]
My schema is defined as below:
const mongoose = require("mongoose");
const schema = new mongoose.Schema({
name: String,
description: String
});
schema.index({ name: "text", description: "text" });
const Items = mongoose.model("Item", schema);

filter data on multiple fields

I am trying to build a filter for JSON object at the moment, the json object looks like this,
created_at: null
deleted_at: null
id: 3
listings: Array(3)
0: {id: 3, name: "Learn the basics of the guitar from the anatomy of the guitar to scales, chords", slug: "learn-the-basics-of-the-guitar-from-the-anatomy-of-the-guitar-to-scales-chords", description: "We live in a unique and wonderful time where elect… going to give you a lifetime of awesome rockin’.", booking_details: "undefined", …}
1: {id: 8, name: "Advanced guitar skills with William Topa", slug: "advanced-guitar-skills-with-william-topa", description: "We live in a unique and wonderful time where elect… going to give you a lifetime of awesome rockin’.", booking_details: "Lorem ipsum dolor sit amet, consectetur adipiscing… laboris nisi ut aliquip ex ea commodo consequat.", …}
2: {id: 9, name: "Music production simplified", slug: "music-production-simplified", description: "We live in a unique and wonderful time where elect… going to give you a lifetime of awesome rockin’.", booking_details: "Lorem ipsum dolor sit amet, consectetur adipiscing… laboris nisi ut aliquip ex ea commodo consequat.", …}
length: 3
__proto__: Array(0)
tag: "Music"
updated_at: null
weight: null
This is part of a bigger object, the hierarchy looks like
[{ data, listings }, {data, listings}]
What I am wanting to do, is filter through the listings array and hide any listings that don't have a cost of "0.00"
Here is what i am trying,
<input type="checkbox" v-model="priceFilter" value="0.00" />
data() {
return {
this.priceFilter: []
}
},
computed: {
filteredTags() {
return this.tags.filter(tag => {
tag.listings.filter(listing => "0.00" === listing.cost);
//console.log(this.checkedPrice, listing.cost);
});
},
},
In the above I just trying to return the listings where the cost matches 0.00 with trigger it via the checkbox being checked but even that does not filter as I wish I still see all listings.
Anyone care to offer any advice?

How can I get the same object in the visitor area as I get in the admin area without the user $uid

Currently on a blog website like I got a problem I didn't expect when I start building it...
I build it like this:
• A admin area where you have to login where you can write/delete articles.
• A public area where you don't need to login where you can see the articles write in the admin area.
My database is build like below as you can see every user got a $uid. So because of how it's build my service look like this:

So When I call the service for get my articles in the admin area I get and in the public area I get.
I find a way to get the value but with this way I lose the key object.
export interface Article {

category: string[],
content: string,
date: string,
image: string,
key: string,
$exists: () => boolean
}
How can I get the same object in the visitor area as I get in the admin area ?

TypeError: Cannot read property 'id' of undefined (REACTJS)

Am still new to Reactjs, thought have tried all I can, but still can't get through this error "TypeError: Cannot read property 'id' of undefined"
please someone help below is my code.
if(this.props.controller === 'location'){

return <Event key= {lol['id']}
descriptions = {lol['description']}
headings = {lol['title']}

With [...Array(this.props.heda[evKey][post])] you create an array which has as the first element the array this.props.heda[evKey][post]).
Maybe you wanted to say [...this.props.heda[evKey][post]] to create a clone of the array?

Because he is not able to find id in this.props.heda[evKey][post] object. So firstly you should console your this.props.heda[evKey][post] object after that I think you will get your actual problem.

Please try below snippet:
this.props.heda.map((evVal, evKey) => {
return evVal.map((postVal, postKey) => {
...
}
}
Now this.props.heda[evKey][postKey] will give you the expected object.

Angular repeating images

New to angular and developing a simple page just to learn the inner workings. What I have is a div that display name price and description along with a button and a full image. What I'm trying to do is underneath that full image display 2-3 additional images. The problem is the same full image is displaying again and none of the additional images are displaying.
Here is the angular
(function () {
var app = angular.module('gemStore', []);
app.controller('StoreController', function () {
this.products = gems;
});
var gems = [
{
name: 'Defmei',
price: 2.95,
description: 'Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. ',
canPurchase: true,
soldOut: false,
images: [
{
image: "Images/image1.jpg",
image: "Images/image2.jpg",
image: "Images/image3.jpg"
}
]
},
{
name: 'Sijoi',
price: 5.95,
description: 'Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. ',
canPurchase: true,
soldOut: true,
images: [
{
image: "Images/image4.jpg",
image: "Images/image3.jpg",
image: "Images/image2.jpg"
}
]
}
]
})();
Here is the HTML
<body data-ng-controller="StoreController as store" >
<div class="display" data-ng-repeat="product in store.products">
<h1>{{product.name}}</h1>
<h2>{{product.price | currency}}</h2>
<p> {{product.description}} </p>
<img class="imageStyles" data-ng-src="{{product.images[0].image}}"/>
<br />
<div data-ng-repeat="image in product.images">
<img data-ng-src="{{image.image}}" class="thumbs" />
</div>
<button data-ng-show="product.canPurchase">Add to cart</button>
</div>
</body>

That image object seems "broken", you're practically redefining the image attribute 3 times.
In javascript, objects have a syntax like { attribName1: attValue1, attribName2: attValue2 ...}
What you're creating here:
images: [
{
image: "Images/image1.jpg",
image: "Images/image2.jpg",
image: "Images/image3.jpg"
}
]
Is an array with 1 item, which is an object, with 1 property, "image", with a value of... "Images/image3.jpg" maybe (or whatever, I wouldn't be surprised if double-defining attributes like this was in fact undefined behaviour).
What you probably want instead is either an array with 3 elements, or an object with 3 distinct attributes, ie:
images: [
{
"image1": "Images/image1.jpg",
"image2": "Images/image2.jpg",
"image3": "Images/image3.jpg"
}
]
You can iterate through array members and object attributes too with ng-repeat, but you have to change your code accordingly.

Your images array only has one item in it with image defined three times. Change it like the following so that there are three separate items and it should work.
images: [
{image: "Images/image4.jpg"},
{image: "Images/image3.jpg"},
{image: "Images/image2.jpg"}
]
