Hi,

Sorry for snuking into your group but I am compltely stuck with  
ElasticSearch and I need help 🙂

I am developping with ROR and the ES Gem.

class Post \< ActiveRecord::Base  
include Elasticsearch::Model  
include Elasticsearch::Model::Callbacks

_Here is my ROR model, anyway..._

```
def self.search(query)
      __elasticsearch__.search(

```

How can I specify wich index I want this function to search in ??  
{  
query:  
here is a complex query  
}  
)  
end

```
  index_name "index_post_search" (I need another index...how can I do 

```

?)

```
  settings index_post_search: { number_of_shards: 1 } do How can I and 

```

another setting to this model ?  
mappings dynamic: 'false' do  
indexes :title, analyzer: 'english', index\_options:  
'offsets'  
indexes :content, analyzer: 'english'  
end  
end  
end

How can I create and update another index ?

Post. **elasticsearch**.client.indices.delete index: "index\_post\_search"  
rescue nil  
Post. **elasticsearch**.client.indices.create index: "index\_post\_search",  
body: { settings: Post.settings.to\_hash, mappings: Post.mappings.to\_hash }  
Post.import

Thk U for your attention !!
