Spring 数据 MongoDB | 分页动态搜索

Question

我正在尝试对大量产品集合进行动态搜索。 object 具有多个属性，包括productName 、 subCategoryName 、 categoryName 、 brandName等。用户可以使用这些属性中的任何一个来搜索产品。 顺序是固定的，搜索字符串的第一优先级是在productName中找到它，然后subCategoryName等等。

我使用aggregate来实现这一点，然后unionWith来连接与其他属性匹配的记录。 当作为原始查询触发时，它似乎可以工作，但我们还需要支持分页，我无法使用 Spring 数据 MongoDB 实现这一点

db.product.aggregate(
[
  { $match: { "productName" : { "$regex" : "HYPER", "$options" : "i"}, 
  "companyNo" : { "$in" : [10000009]}, "status" : { "$in" : ["ACTIVE", "IN_ACTIVE", "OUT_OF_STOCK"]} }},
  { $unionWith: { coll: "product", pipeline: [{ $match: { "subCategoryName" : { "$regex" : "HYPER", "$options" : "i"},
  "companyNo" : { "$in" : [10000009]}, "status" : { "$in" : ["ACTIVE", "IN_ACTIVE", "OUT_OF_STOCK"]}} }] } },
  { $unionWith: { coll: "product", pipeline: [{ $match: { "categoryName" : { "$regex" : "HYPER", "$options" : "i"}, 
  "companyNo" : { "$in" : [10000009]}, "status" : { "$in" : ["ACTIVE", "IN_ACTIVE", "OUT_OF_STOCK"]}} }] } },
  { $unionWith: { coll: "product", pipeline: [{ $match: { "brandName" : { "$regex" : "HYPER", "$options" : "i"},
  "companyNo" : { "$in" : [10000009]}, "status" : { "$in" : ["ACTIVE", "IN_ACTIVE", "OUT_OF_STOCK"]}} }] } },
]
)

此外，此查询仅在我们传递确切名称的 substring 时才有效。 例如，如果我使用NIVEA BODY LOTION搜索，将返回NIVEA BODY LOTION EXPRESS HYDRATION 200 ML HYPERmart产品，但如果我使用HYDRATION LOTION搜索，则不会返回任何内容

样品产品：

    "_id" : ObjectId("6278c1c2f2570d6f199435b2"),

    "brandName" : "HYPERMART",
    "productName" : "NIVEA BODY LOTION EXPRESS HYDRATION 200 ML HYPERmart",
    "productImageUrl" : "https://shop-now-bucket.s3.ap-south-1.amazonaws.com/shop-now-bucket/qa/10000009/product/BEAUTY%20%26%20PERSONAL%20CARE/HYPERMART/NIVEA%20BODY%20LOTION%20EXPRESS%20HYDRATION%20200%20ML/temp1652081080302.jpeg",
