ElasticSearch + Tire searching only on id field

Question

I've looked everywhere but nothing can help me. And I can't figure out what is the problem.

my model

class Article
 include Mongoid::Document
 include Mongoid::Timestamps


 include Tire::Model::Search
 include Tire::Model::Callbacks
  mapping do
    indexes :_id, :index => :not_analyzed
    indexes :title
    indexes :body
  end


 def to_indexed_json
   self.to_json
 end

http://localhost:9200/articles/_mapping
{
  "articles": {
    "article": {
      "properties": {
        "$oid": {
          "type": "string"
        },
        "body": {
          "type": "string"
        },
        "title": {
          "type": "string"
        }
      }
    }
  }
}

Article.search 'love' gives no results,but there are Article with title "love", I've tried to build many requests but nothing works.

all times the same results:

"hits"=>{"total"=>0, "max_score"=>nil, "hits"=>[]}}

But If I type: Article.search "cbc267c955464f22d72a0100" it gives me article with title: "love"

So it seems to me that tire create indexes only on ID field, regardless mapping indexes on model.

When I recreate indexes

Article.index_name
  => "articles" 
Tire.index('articles').delete
  => true 
Article.import

my mapping becomes:

{
  "articles": {
    "article": {
      "properties": {
        "$oid": {
          "type": "string"
        }
      }
    }
  }
}

UPDATED

module BSON
  class ObjectId
    def as_json(*args)
      to_s()
    end

    def to_json(*args)
      MultiJson.encode(as_json())
    end
  end
end

After implementing this initialize, all seems to work fine

I too encountered such problems while using tire . After deleting the index, you can try Article.create_elasticsearch_index and Article.tire.index.import Article.all .

The _source field in your indexed document should have title , id and body included in it, which should make it available for search.

Anyways, tire is getting retired as elasticsearch gem has now been released.
