Elasticsearch：从轮胎到Elasticsearch持久性迁移

Question

我想从Tire（retire）gem迁移到Elasticsearch Persistence gem，在Tyre中，我曾经从模型内部设置索引设置，如下所示

settings :number_of_shards => 5,
        :number_of_replicas => 1,
        :analysis => {
          :analyzer => {
            :my_pattern => {
               "type"         => "custom",
                "tokenizer" => "keyword",
                 "filter"    =>  ["url_ngram", "lowercase"]
               }
          }, :filter => {
       :url_stop => {
         :type => "stop",
         :stopwords => ["="]
       },
       :url_ngram => {
         :type => "nGram",
         :min_gram => 4,
         :max_gram => 40
       }
       }

        } do
 mapping {

   indexes :msgpriority, :type => 'string',      :analyzer => 'snowball'
   indexes :msghostname, :type => 'string',        :analyzer => 'snowball'
   indexes :msgtext, :type => 'string',        :analyzer => 'my_pattern'
   indexes :msgdatetime,  :type => 'date',       :include_in_all => false
 }
end

现在，我正在使用存储库对象，并且我想应用相同的设置（主要是分析器）

即使更改了分片的数量，就像我什么都没写一样，下面的代码也不起作用

REPOSITORY = Elasticsearch::Persistence::Repository.new do
# Configure the Elasticsearch client
client Elasticsearch::Client.new url: ENV['ELASTICSEARCH_URL'], log: true
now_time = Time.now
# Set a custom index name
index "ip_logstreams_#{now_time.year}_#{now_time.month}_#{now_time.day}"

# Set a custom document type
type  :log_entry

# Specify the class to inicialize when deserializing documents
klass LogEntry

# Configure the settings and mappings for the Elasticsearch index
settings number_of_shards: 2, :analysis => {
 :analyzer => {
   :my_pattern => {
    "type"         => "custom",
    "tokenizer" => "keyword",
    "filter"    =>  ["url_ngram", "lowercase"]
  }
  }, :filter => {
    :url_stop => {
      :type => "stop",
      :stopwords => ["="]
      },
    :url_ngram => {
      :type => "nGram",
      :min_gram => 4,
      :max_gram => 40
    }
  }

  } do
    mapping {

      indexes :msgpriority, :type => 'string',      :analyzer => 'snowball'
      indexes :msghostname, :type => 'string',        :analyzer => 'snowball'
      indexes :msgtext, :type => 'string',        :analyzer => 'my_pattern'
      indexes :msgdatetime,  :type => 'date',       :include_in_all => false
    }
  end
end

更新：

当我发出

REPOSITORY.create_index! force: true

应用了更改，但我认为elasticsearch中的设置被弄乱了，如屏幕截图所示（从head插件获取）

Answer 1

您是否考虑过仅使用elasticsearch / elasticsearch-model-它提供了自动回调 ，旨在帮助您持久保存数据。

Answer 2

在Elasticsearch gem中使用存储库对象时，我们应该发出

REPOSITORY.create_index!

这将使用提供的设置创建索引，您可以添加force: true如果要再次重新创建索引，则为force: true
