Searching from two tables (Post and Lecture) and combining the result.

Route::post('/search',function(){
    $q = Input::get ( 'q' );
    $post = App\Post::where('title','LIKE','%'.$q.'%')->get();
    $lecture = App\Lecture::where('title','LIKE','%'.$q.'%')->get();
    $merged = $post->merge($lecture);
    if(count($merged) > 0){
        return view('searchResult')->withDetails($merged)->withQuery ( $q );
    }
    else {
        return view ('searchResult')->withMessage('No Details found. Try to search again !');
    }
});

2) resources->views->searchresult.blade.php

<form class="navbar-form navbar-left" role="search" action="/search" method="POST">

      <div class="input-group">
        <input type="text" class="form-control" placeholder="Search" name="q">
        <div class="input-group-btn">
          <button class="btn btn-default" type="submit">
            <i class="glyphicon glyphicon-search"></i>
          </button>
        </div>
      </div>
 </form>
