工作：环境：

Rails 4.1
Searchkick 2.3.2

我将在控制台中执行以下查询：

res = Searchkick.search(
        "Thom",
        index_name: [Customer.searchkick_index.name, User.searchkick_index.name],
        match: :word_start,
        fields: [:first_name, :last_name, :name],
        limit: 10,
        #load: false,
        misspellings: {below: 3}
        )

res.hits 看起来像：

=> [
{"_index"=>"customers_production_20180830135206573", "_type"=>"customer", "_id"=>"162", "_score"=>66.72488}, 
{"_index"=>"customers_production_20180830135206573", "_type"=>"customer", "_id"=>"547", "_score"=>63.447693}, 
{"_index"=>"users_production_20170616114857320", "_type"=>"user", "_id"=>"447", "_score"=>59.895348}, 
{"_index"=>"users_production_20170616114857320", "_type"=>"user", "_id"=>"412", "_score"=>58.541008}, 
{"_index"=>"users_production_20170616114857320", "_type"=>"user", "_id"=>"338", "_score"=>57.721336}, 
{"_index"=>"users_production_20170616114857320", "_type"=>"user", "_id"=>"271", "_score"=>42.91793}, 
{"_index"=>"users_production_20170616114857320", "_type"=>"user", "_id"=>"315", "_score"=>42.91793}, 
{"_index"=>"users_production_20170616114857320", "_type"=>"user", "_id"=>"201", "_score"=>42.91793}
]

一切都按预期进行。我在搜索框中输入我的字词，然后我得到了结果。

res.first
 => #<Customer id: 162, field: yada-yada>

升级后：

Rails 5.2
Searchkick 4.4.1

我做同样的查询，我得到了以下命中

res.hits：

[
{"_index"=>"customers_staging_20200920170910290", "_type"=>"_doc", "_id"=>"162", "_score"=>83.6008},       
{"_index"=>"customers_staging_20200920170910290", "_type"=>"_doc", "_id"=>"547", "_score"=>79.819855},       
{"_index"=>"users_staging_20200920175208885", "_type"=>"_doc", "_id"=>"412", "_score"=>79.099915},       
{"_index"=>"users_staging_20200920175208885", "_type"=>"_doc", "_id"=>"201", "_score"=>67.04228},       
{"_index"=>"users_staging_20200920175208885", "_type"=>"_doc", "_id"=>"315", "_score"=>67.04228},       
{"_index"=>"users_staging_20200920175208885", "_type"=>"_doc", "_id"=>"338", "_score"=>67.04228}
]

res.first
Searchkick::Error: Unknown model for index: customers_staging_20200920170910290
from /home/deploy/.rvm/gems/ruby-2.6.5/gems/searchkick-4.4.1/lib/searchkick/results.rb:37:in `block in with_hit'

这是我在模型中的设置：

include Elasticsearch::Model <-- Added after upgrade
include Elasticsearch::Model::Callbacks <-- Added after upgrade
searchkick match: :word_start, searchable: [:name]
scope :search_import, -> {includes(:user)}

我能否得到任何帮助来确定发生这种情况的原因？

Searchkick::Error: Unknown model for index: customers_staging_20200920170910290
from /home/deploy/.rvm/gems/ruby-2.6.5/gems/searchkick-4.4.1/lib/searchkick/results.rb:37:in `block in with_hit'

谢谢

【解决方案1】：

我发现了问题。

在文档中：

多个模型搜索多个模型：

Searchkick.search "milk"，型号：[产品，类别]

如此变化：

index_name: [Customer.searchkick_index.name, User.searchkick_index.name]

到

models: [Customer, User]

解决了我的问题。
