Filter Service with Elasticsearch

Definition of Filter Types

When using elasticsearch as Product Index, different FilterTypes must be configured for the corresponding tenant. These filter types create the elasticsearch specific conditions for each filter.

Here is an example for the configuration:

pimcore_ecommerce_framework:
    filter_service:
        tenants:
            ElasticSearch:
                filter_types:
                    FilterNumberRange:
                        # Service id for filter type implementation
                        filter_type_id: Pimcore\Bundle\EcommerceFrameworkBundle\FilterService\FilterType\ElasticSearch\NumberRange
                        # Default template for filter, can be overwritten in filter definition
                        template: ':Shop/filters:range.html.php'

                    FilterNumberRangeSelection:
                        filter_type_id: Pimcore\Bundle\EcommerceFrameworkBundle\FilterService\FilterType\ElasticSearch\NumberRangeSelection
                        template: ':Shop/filters:numberrange.html.php'

                    FilterSelect:
                        filter_type_id: Pimcore\Bundle\EcommerceFrameworkBundle\FilterService\FilterType\ElasticSearch\Select
                        template: ':Shop/filters:select.html.php'

                    FilterSelectFromMultiSelect:
                        filter_type_id: Pimcore\Bundle\EcommerceFrameworkBundle\FilterService\FilterType\ElasticSearch\SelectFromMultiSelect
                        template: ':Shop/filters:select.html.php'

                    FilterMultiSelect:
                        filter_type_id: Pimcore\Bundle\EcommerceFrameworkBundle\FilterService\FilterType\ElasticSearch\MultiSelect
                        template: ':Shop/filters:multiselect.html.php'

                    FilterMultiSelectFromMultiSelect:
                        filter_type_id: Pimcore\Bundle\EcommerceFrameworkBundle\FilterService\FilterType\ElasticSearch\MultiSelectFromMultiSelect
                        template: ':Shop/filters:multiselect.html.php'

                    FilterMultiRelation:
                        filter_type_id: Pimcore\Bundle\EcommerceFrameworkBundle\FilterService\FilterType\ElasticSearch\MultiSelectRelation
                        template: ':Shop/filters:multiselect-relation.html.php'

                    FilterCategory:
                        filter_type_id: Pimcore\Bundle\EcommerceFrameworkBundle\FilterService\FilterType\ElasticSearch\SelectCategory
                        template: ':Shop/filters:select_category.html.php'

                    FilterRelation:
                        filter_type_id: Pimcore\Bundle\EcommerceFrameworkBundle\FilterService\FilterType\ElasticSearch\SelectRelation
                        template: ':Shop/filters:object_relation.html.php'
