How do I create a Search using a Model and a Controller in Laravel 8?

So I am creating a medical app for a school project. I am fairly new to Laravel and even though I've learnt some things so far in it, I am stuck with creating a Search engine for users to search by disease name and symptom. I used Voyager for my admin panel and Jetstream for scaffolding. Livewire is also present. I have a database table called Diagnoses with columns such as name, description, types, symptoms, causes, treatments, advice. After a user logs in and reaches the dashboard (dashboard.blade.php) I want there to be a Search form where they can search for by name and symptom then display the results like a typical search should do.

Table that I want the results from

Table name = Diagnoses, Model = Diagnose, Controller = DiagnoseController.php

How can I accomplish this? Here are the codes that I think I should be working with:

web.php:

Route::get('/', function () {
return view('main');
});

Route::middleware(['auth:sanctum', 'verified'])->get('/dashboard', function () {
return view('dashboard');
})->name('dashboard');

Route::group(['prefix' => 'admin'], function () {
Voyager::routes();
});

Route::get("/about", function () {
return view('about');
});

Route::get("/contact", function () {
return view('contact');
});

Model Diagnose.php:

<?php

namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Diagnose extends Model
{
    use HasFactory;
}

Controller DiagnoseController.php:

<?PHP

namespace App\Http\Controllers;

use App\Model\
use Illuminate\Http\Request;

class DiagnoseController extends Controller
{
   //
}

Views dashboard.blade.php:

<x-app-layout>
<x-slot name="header">
    <h2 class="font-semibold text-xl text-gray-800 leading-tight">
        {{ __('Dashboard') }}
    </h2>
</x-slot>

<div class="py-12">
    <div class="max-w-7xl mx-auto sm:px-6 lg:px-8">
        <div class="bg-white overflow-hidden shadow-xl sm:rounded-lg">

        *Put code here*
        

        </div>
    </div>
</div>
</x-app-layout>

Yes, I am a novice so that's why I am seeking help. Also if there is a better way or easier way then please show me. Thanks in advance.
