ElasticSearch Rails - Setting a Custom Analyzer - ruby-on-rails

Question

I'm using ElasticSearch in Rails 4 through elasticsearch-rails (https://github.com/elasticsearch/elasticsearch-rails)
I have a User model, with an email attribute.
I'm trying to use the 'uax_url_email' tokenizer described in the docs:
class User < ActiveRecord::Base
include Elasticsearch::Model
include Elasticsearch::Model::Callbacks
settings analysis: { analyzer: { whole_email: { tokenizer: 'uax_url_email' } } } do
mappings dynamic: 'false' do
indexes :email, analyzer: 'whole_email'
end
end
end
I followed examples in the wiki (https://github.com/elasticsearch/elasticsearch-rails/wiki) and the elasticsearch-model docs (https://github.com/elasticsearch/elasticsearch-rails/wiki) to arrive at this.
It doesn't work. If I query elasticsearch directly:
curl -XGET 'localhost:9200/users/_mapping
It returns:
{
"users": {
"mappings": {
"user": {
"properties": {
"birthdate": {
"type": "date",
"format": "dateOptionalTime"
},
"created_at": {
"type": "date",
"format": "dateOptionalTime"
},
"email": {
"type": "string"
},
"first_name": {
"type": "string"
},
"gender": {
"type": "string"
},
"id": {
"type": "long"
},
"last_name": {
"type": "string"
},
"name": {
"type": "string"
},
"role": {
"type": "string"
},
"updated_at": {
"type": "date",
"format": "dateOptionalTime"
}
}
}
}
}
}

This ended up being an issue with how I was creating the index. I was trying:
User.__elasticsearch__.client.indices.delete index: User.index_name
User.import
I expected this to delete the index, then re-import the values. However I needed to do:
User.__elasticsearch__.create_index! force: true
User.import
