【问题描述】：

我有这两个搜索

foods = Food.search name, fields: [:name], where: {
   or: [
    [{nutritionist_id: nil}, {nutritionist_id: current_nutritionist_id}]
   ]
}, order: {_score: :desc}

recipes = Recipe.search name, fields: [:recipe_name], where: {
   or: [
        [{nutritionist_id: nil}, {nutritionist_id: current_nutritionist_id}]
      ]
 }, order: {_score: :desc}

我希望 foods 和 recipes 以相同的结果返回。就像合并它们，类似上面的东西或其他更好的方法。

return foods + reciples

【解决方案1】：

我通过Searchkick.search 解决了这个问题而不是：

foods = Food.search name, fields: [:name], where: {
   or: [
    [{nutritionist_id: nil}, {nutritionist_id: current_nutritionist_id}]
   ]
}, order: {_score: :desc}

和

recipes = Recipe.search name, fields: [:recipe_name], where: {
   or: [
        [{nutritionist_id: nil}, {nutritionist_id: current_nutritionist_id}]
      ]
 }, order: {_score: :desc}

我用过。

result = Searchkick.search(name, index_name: [Food, Recipe], fields: [:name, :recipe_name], 
  where: {
      _or: [ {nutritionist_id: nil}, {nutritionist_id: current_nutritionist_id} ]
  }, order: {_score: :desc})
result

这样 Searchkick 在这两个模型中搜索 Food 和 Recipe 并返回包含两个结果的数组。
