Java-具有多个节点的树数据结构-如何有效搜索

我正在为某些类别和子类别搜索实现/数据结构。我正在考虑使用搜索树，但不确定如何开始实施。

让我告诉您数据的样子。它从后端以json结构的形式出现在我的头上，但它看起来像这样：

  [
    {
      "id": 94,
      "category_name": "New In", //this is the category category_name
      "description": "",
      "children": [ //this is the category children which can also be a sub-category
        {
          "id": 322,
          "category_name": "New Studio",
          "description": "Chic, sophisticated and polished with a classic edge."
        },
        {
          "id": 365,
          "category_name": "New Soho",
          "description": "Fresh, eclectic, and trendy. Oozes effortless cool."
        },
        {
          "id": 809,
          "category_name": "Summer Collection",
          "description": "Your ultimate summer look"
        }
      ]
    },
    {
      "id": 12,
      "category_name": "Clothes",
      "description": "",
      "children": [
        {
          "id": 22,
          "category_name": "All Clothes",
          "description": ""
        },
        {
          "id": 63,
          "category_name": "Tops",
          "description": "",
          "children": [
            {
              "id": 5,
              "category_name": "All Tops",
              "description": ""
            }

          ]
        },
        {
          "id": 641,
          "category_name": "Accessories",
          "description": "",
          "children": [
            {
              "id": 61,
              "category_name": "All Accessories",
              "description": ""
            },
            {
              "id": 622,
              "category_name": "Jewelry",
              "description": "",
              "children": [ // here is an example of a child that is a sub-category also
                {
                  "id": 52,
                  "category_name": "All Jewelry",
                  "description": ""
                },
                {
                  "id": 68,
                  "name": "Necklaces",
                  "description": ""
                },
                {
                  "id": 69,
                  "name": "Bracelets",
                  "description": ""
                },

              ]
            },

  ]

因此，如果我必须将其绘制出来，它将看起来像这样：

因此，我希望能够找到任何东西。因此，例如，如果我要搜索项链，那么我也希望获得一条项链以获取以下路径：类别/配件/珠宝/项链

Is there a built in data structure for this ? i am coding in java. I suppose i also need the nodes sorted in some kind of order maybe A-Z.

so far i have this:

class Node{
 String label;
 List<Node> children;
}

but then how to search ? and is there a better data structure ? I do not want to iterate over all the nodes during a search, is there a way to sort the tree so i dont have to do that ? How i have it now i'd have to iterate over all the children. is there a way to maybe sort alphaetically perhaps or some kind of sort that would make the lookup faster ?
