And the controller function

public function getSearch(Request $request) { 
    $keyword = $request->input('keyword'); 
    $categories = Category::all(); 
    if( $keyword != ""){ 
        return view('store.search')->with('posts', Post::where('title', 'LIKE', '%'.$keyword.'%')->get()) 
            ->with('keyword', $keyword) 
            ->with('categories', $categories); 
     } 
     else { 
         return redirect('/') ; 
     } 
}
