Unable to set custom analysers

[aash dhariya]

Here is my result of query:

     curl -XGET localhost:9200/_template/template_1  

{"template":"*", "order":0, "settings":{

    "number_of_shards":1,

    "analysis":{

        "tokenizer":{

            "name_tokenizer":{

                "type":"edgeNGram",

                "max_gram":100,

                "min_gram":3,

                "side":"front"

            }

        },

        "analyzer":{

            "name_analyzer":{

                "tokenizer":"whitespace",

                "type":"custom",

                "filter":["lowercase", "multi_words", "name_filter"]

            },

            "lower_keyword":{

                "tokenizer":"keyword",

                "type":"custom",

                "filter":["lowercase"]

            },

            "multi_words":{

                "tokenizer":"standard",

                "type":"custom",

                "filter":["standard", "lowercase", "stop", "multi_words"]

            }

        },

        "filter":{

            "multi_words":{

                "type":"shingle",

                "min_shingle_size":2,

                "max_shingle_size":1

            },

            "name_filter":{

                "type":"edgeNGram",

                "max_gram":100,

                "min_gram":3,

                "side":"front"

            },

            "name_filter_reverse":{

                "type":"edgeNGram",

                "max_gram":100,

                "min_gram":3,

                "side":"back"

            }

        }

    }

}, "mappings":{

    "type1":{

        "_source":{

            "enabled":false

        }

    }

}}

Now, I can use analysers - "name_analyzer" for a field in elastictastic document. Here is my model class

    tag.rb

    field :tag_value, type: 'string', index: 'analyzed', analyzer: 'name_analyzer' do

      field :tag_value_lower, type: 'string', index: 'analyzed', analyzer: 'lower_keyword'

      field :tag_value_untouched, type: 'string', index: 'not_analyzed'

    end

  

When I perform:

 

    Tag.sync_mapping

I get the following error:

    Elastictastic::ServerError::MapperParsingException: [Analyzer [name_analyzer] not found for field [tag_value]]

    from /home/geeky-sh/.rvm/gems/ruby-1.9.3-p327/bundler/gems/elastictastic-0652e1cf11ff/lib/elastictastic/middleware.rb:75:in `raise_error'

Any reasons on why I am unable to set mappings using my custom analyzers?

Did you get this sorted out? I noticed you opened an issue and then closed it. Anyway, one thing that comes to mind is that you need to create your index *after* setting up your template -- is that the order you did things in?

These are the steps that were followed by me:

1. Deleting the template that I already have:

    curl -XDELETE localhost:9200/_template/template_1

2. Deleting the previous elastictastic documents and its index:

Tag.destroy_all

3. Resetting the template:

curl -XPUT localhost:9200/_template/template_1 -d '#{json data}'

4. Checking if the template is set:

curl -XGET localhost:9200/_template/template_1

# template is set

5. Sync mapping now:

Tag.sync_mapping

Are there any other steps that I am missing?

Hi Aash,

Yes -- step 2 doesn't actually delete the index; it just destroys all the Tag documents in the index. You'll need to do curl -XDELETE localhost:9200/my_index as step 2.5. That way when you re-create the index, it will take the settings from your template.
