Question

我有产品数据库，我使用Thinking Sphinx来搜索它们。我有一套相当复杂的条件，可以在正确的类别和细节中找到合适的产品。但是，我想改进搜索，以便我可以限制产品的价格和数量，这两者都是产品型号的浮动属性。

例如：

1.9.2p290 :014 > Product.search('eggs').map { |p| "#{p.name}, $#{p.price}" }
  Sphinx Query (4.6ms)  eggs
  Sphinx  Found 984 results
  Product Load (0.9ms)  SELECT "products".* FROM "products" WHERE "products"."id" IN (7635, 7636, 7637, 7638, 7639, 7640, 7641, 7642, 7643, 7644, 7645, 7646, 7647, 7648, 7650, 7651, 7652, 7653, 7654, 7655)

在TS查找匹配文本后，如何使用ActiveRelation优化搜索？

Answer 1

这应该有效：

Product.search 'eggs', :with => {:price => price, :quantity => quantity}

假设您有三个不同的输入框来定义搜索字符串（'eggs'），price和quantity，我会在尝试搜索完全匹配时使用类似的内容：

scope = params[:query].present? Product.search params[:query] : scope = Product.search nil

scope = scope.search with: { :price => params[:price] } if params[:price].present?
scope = scope.search with: { :price => params[:quantity] } if params[:quantity].present?

@products = scope

但是，不会过滤'价格低于x'或'x和y之间的数量'。为此，你需要使用范围，因为思考 - 狮身人面像。例如，如果要搜索价格低于给定值的产品：

Product.search 'eggs', :with => {:price => 0..value}

返回与查询'eggs'匹配的产品，其价格介于0和给定值之间。

如果您要搜索价格高于给定值的产品：

Product.search 'eggs', :with => {:price => value..Float::MAX}

返回与查询'eggs'匹配的产品，其价格介于给定值和最大可表示有限浮点数之间。
