Add the following route code in the “routes/web.php” file.

<?php
 
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
 
Route::view('search','livewire.home');

<?php

|--------------------------------------------------------------------------

| Web Routes

|--------------------------------------------------------------------------

| Here is where you can register web routes for your application. These

| routes are loaded by the RouteServiceProvider within a group which

| contains the "web" middleware group. Now create something great!

Route::view('search','livewire.home');

Step 8: Create Blade Files

So finally, first we will open the home.blade.php and search.blade.php files and after then paste the following code.
resources/views/livewire/home.blade.php
