Php 在Laravel中使用雄辩的ORM，使用'；非regexp'；

我处理的是按slug分类搜索，我想排除结尾包含破折号和数字的结果（比如：powerbank-1）。 我的问题是：

$categories = Category::where('active_products', ">", 0)
    ->where('slug', 'LIKE', "%$search_term%")
    ->where('slug', 'not regexp', "/$search_term-[0-9]/")
    ->get();

我的结果仍然包含不需要的结果，slug中有-1和-2个结尾：

{
  "query": "powerbank",
  "categories": [
  {
    "id": 18,
    "parent_id": 17,
    "lft": 108,
    "rgt": 109,
    "depth": 1,
    "name": "Powerbank",
    "description": null,
    "description2": null,
    "products": 43,
    "active_products": 38,
    "created_at": "2016-08-25 20:51:42",
    "updated_at": "2016-09-20 06:06:06",
    "slug": "powerbank"
  },
  {
    "id": 20,
    "parent_id": 19,
    "lft": 124,
    "rgt": 125,
    "depth": 1,
    "name": "Powerbank",
    "description": null,
    "description2": null,
    "products": 43,
    "active_products": 38,
    "created_at": "2016-08-25 20:51:43",
    "updated_at": "2016-09-20 06:06:06",
    "slug": "powerbank-1"
  },
  {
    "id": 22,
    "parent_id": 21,
    "lft": 136,
    "rgt": 137,
    "depth": 1,
    "name": "Powerbank",
    "description": null,
    "description2": null,
    "products": 43,
    "active_products": 38,
    "created_at": "2016-08-25 20:51:43",
    "updated_at": "2016-09-20 06:06:06",
    "slug": "powerbank-2"
  }]
}
