Find Objects with particular tag

Hi there I cant find it or it doesnt exist, i would like to see all objects in the hierachy only containing a certain tag, is this possible??

well i cannot find a way to show only particular objects in hierarchy but i found a way to see the list of objects in a custom window and select the objects using that window in the hierarchy.

using UnityEngine;
using System.Collections;
using UnityEditor;

public class TagSearcher : EditorWindow {
 
 static TagSearcher window;
 static string tagValue="";
 static string oldTagValue;
 static Vector2 scrollValue=Vector2.zero;
 static GameObject[] searchResult;
 
 [MenuItem("EditorUtility/TagSearcher")]
 static void OpenTagSearcher()
 {
        
 
     window = (TagSearcher)EditorWindow.GetWindow (typeof (TagSearcher));
     searchResult =  GameObject.FindGameObjectsWithTag(tagValue);
 
   
 }
 
 void OnGUI()
 {
 
 
    oldTagValue=tagValue;
 
    tagValue=EditorGUILayout.TagField(tagValue); 
 
 
    if(tagValue != oldTagValue)
    {
 
 
       searchResult = GameObject.FindGameObjectsWithTag(tagValue);
       Selection.objects = searchResult;
 
    }
 
    scrollValue=EditorGUILayout.BeginScrollView(scrollValue);
 
    if(searchResult != null)
    {
 
       foreach(GameObject obj in searchResult)
       { 
          if(obj !=null)
          {
             if(GUILayout.Button(obj.name))//,GUIStyle.none))
             {
                 Selection.activeObject =  obj; 
                 EditorGUIUtility.PingObject(obj);
             } 
         }
         else
         {
             searchResult = GameObject.FindGameObjectsWithTag(tagValue);
             Selection.objects = searchResult;
             break;
         }
     }
 
  }
 
  EditorGUILayout.EndScrollView();
  } 
 
}

By default it will select all objects with that tag. but you can select the individual objects also using the window.

You can see object by component just by adding :

t:mycomponent in the search field or you can do something like Seth said :
