Use of type "constant_keyword"

[VinceSchlo]

Hi everyone,

I'm currently trying to use the constant_keyword type to split my index by country.

I'm using v6.1.0 of FOSElasticaBundle

Here is an example of my indexe's declaration in fos_elastica.yaml:

fos_elastica:
    indexes:

        app.orders_be:
            index_name: '%env(ELASTICSEARCH_INDEX_PREFIX)%.orders_be'
            persistence:
                driver: orm
                model: App\Entity\CommandeAppro
                provider: ~
                listener:
                    defer: false
                    logger: true
                repository: App\Elastica\Repository\CommandeApproElasticaRepository
                elastica_to_model_transformer:
                    query_builder_method: createSearchQueryBuilder
                    ignore_missing: true
                finder: custom_transformed_finder.orders_be
            properties:
                <<: *order_properties
                country:
                    property_path: getCountryIsoCode
                    type: constant_keyword
                    value: BE
            settings:
                number_of_shards: 10

        app.orders_gb:
            index_name: '%env(ELASTICSEARCH_INDEX_PREFIX)%.orders_gb'
            persistence:
                driver: orm
                model: App\Entity\CommandeAppro
                provider: ~
                listener:
                    defer: false
                    logger: true
                repository: App\Elastica\Repository\CommandeApproElasticaRepository
                elastica_to_model_transformer:
                    query_builder_method: createSearchQueryBuilder
                    ignore_missing: true
                finder: custom_transformed_finder.orders_gb
            properties:
                <<: *order_properties
                country:
                    property_path: getCountryIsoCode
                    type: constant_keyword
                    value: GB
            settings:
                number_of_shards: 10

I use custom finder, so it is my services.yaml :

custom_transformed_finder.orders_gb:
       class: App\Finder\CustomTransformedFinder
       arguments:
           - '@fos_elastica.index.app.orders_gb'
           - '@fos_elastica.elastica_to_model_transformer.app.orders_gb'

   custom_transformed_finder.orders_be:
       class: App\Finder\CustomTransformedFinder
       arguments:
           - '@fos_elastica.index.app.orders_be'
           - '@fos_elastica.elastica_to_model_transformer.app.orders_be'

Each index is well created, with good data but the search isn't working that well. Indeed, after digging a bit into the code I think I found that the finder are related to the entity and not the index so on only the last one describe into the fos_elastica.yaml config file will be associated, ignoring/erasing the previous one.

If I search BE (Belgian) order, it works fine but if i try to search for GB (Great Britain) the BE finder is still used.

Am I wrong somewhere at using this ElasticSearch feature or is it unusable at this time due to the way the library is write ?
