Step:1 Create a simple form 

 <form action="{{route('PostSearch')}} ">
     <div >
       <label ><strong >Eye color </strong></label>
          <div >
             <div >
               <select name=eye_color>
                  <option value="">Not Given</option>
                  <option value="Blue" >Blue</option>
                  <option value="Brown" >Brown</option>
                  <option value="Green">Green</option>
                  <option value="Hazel" >Hazel</option>
                  <option value="Grey" >Grey</option>
                  <option value="Dark brown">Dark brown</option>
                  <option value="Rather not say" >Rather not say</option>
                  <option value="Other">Other</option>
               </select>
             </div>
           </div>
     </div>



       <div >
           <label ><strong >Smoke </strong></label>
              <div >
               <div >
                 <select name=smoke>
                 <option value="" >Not Given</option>
                 <option value="No" >No</option>
                 <option value="Yes, socially" >Yes, socially</option>
                 <option value="Yes, regularly" >Yes, regularly</option>
                 <option value="Rather not say" >Rather not say</option>
                 </select>
               </div>
              </div>
            </div>



</form>

Step: 2 SearchController.php

 public function PostSearch(Request $request)
 {

     $filters = [
            'eye_color' => Input::get('eye_color'),
            'drink'    => Input::get('drink'),
        ];
     
      $user = User::where(function ($query) use ($filters) {
            if ($filters['eye_color']) {
                $query->where('eye_color', '=', $filters['eye_color']);
            }
             if ($filters['smoke']) {
                $query->where('smoke', '=', $filters['smoke']);
            }
        })->get();

    return $user;
  }

Here we try to show with two fields, the query filter eye_color  apply on the filter when user select. so here we complete post on Laravel advance search filters with optional fields.
