我在我的导轨项目中使用轮胎和弹性搜索，这是一个汽车零件的零售网站。 ES正在为用于浏览零件目录的分面搜索页面供电。我的问题是：如何使用查询字符串搜索相同字段时，术语过滤器仅返回完全匹配，仅在查询字符串上使用分析器？
我希望这是有道理的。我将尝试提供一个例子：
有问题的模型/索引称为零件。假设某个部件具有名为categories和sub_categories的映射。如果用户选择Brake 类别和Brake Caliper Carrier 子类别（创建术语过滤器），我必须确保Brake Caliper 子类别中的部件也不会返回 - 它是一个单独的子类别。但是，我希望用户能够在搜索字段中输入类似“刹车”的内容（创建一个query_string），并从所有这些类别中的产品中获取结果。
以下是零件模型中的相关代码：
def to_indexed_json
fits = fitments.try(:map) do |fit|
{
make: fit.try(:make).try(:name),
make_id: fit.try(:make).try(:id),
model: fit.try(:model).try(:name),
model_id: fit.try(:model).try(:id),
year: fit.year,
sub_model: fit.sub_model
}
end
{
id: id,
name: name,
description: description,
fitments: fits,
categories: root_categories,
sub_categories: sub_categories,

condition_id: condition_id,

thumb_url: part_images.first.try(:image).try(:thumb).try(:url),
city: user.try(:city),
inventory: inventory,
part_number: part_number,
user: user.try(:public_name)
}.to_json
end
