Sitecore Query

I have come to known this issue whereby Sitecore Query limit the search by default to 100. This means potentially we will get less results than expected. Recently, I have come across a solution where the Query max item is tweaked on the fly.

here is the sample code

/// 

  /// Set Query.MaxItems unlimit
  /// Reference : http://blog.bylectric.net/2009/07/sitecore-and-query-maxitems-setting/
  /// 
  /// 
  /// 
  /// 
  public static Item[] QueryItemsWithoutLimit(string queryString , Item startRoot )
  {
   if (string.IsNullOrEmpty(queryString) || startRoot == null)
    return null;
   
   Query query = new Query(queryString);
   query.GetType().GetField("m_max", BindingFlags.Instance | BindingFlags.NonPublic).SetValue(query, 0);
   Object result = query.Execute(startRoot);
   QueryContext qc = result as QueryContext;
   QueryContext[] qcArray = result as QueryContext[];

   var database = global::Sitecore.Context.ContentDatabase ?? global::Sitecore.Context.Database;
   if (qcArray != null && qcArray.Length > 0)
   {
    Item[] itemArray = new Item[qcArray.Length];
    for (int i = 0; i < qcArray.Length; i++)
    {
     itemArray[i] = database.Items[qcArray[i].ID];
    }
    return itemArray;
   }

   if (qc != null)
    return new Item[] { database.Items[qc.ID] };
   return null; 
  }
