Unrecognized option "types" | FOS Elastica & Symfony

Question

I am able to create indexes 1 by 1 but my purpose is to have 1 big index with subindexes to search. (I am reproducing an existing app but upgrading dependencies)

Symfony : 5.4* FOS-Elastica : 6.1 Elastic : 7*

This is my error message and if I change types to properties I have similar errors. I have been trying to switch and indent differently all day:

Unrecognized option "types" under "fos_elastica.indexes.app". Available options are "_id", "_routing", "_source", "analyzer", "client", "date_detection", "dynamic", "dynamic_date_formats", "dynamic_templates", "finder", "index_   
  name", "index_prototype", "indexable_callback", "numeric_detection", "persistence", "properties", "serializer", "settings", "use_alias".   

What am I doing wrong please ?

Answer 1

So I was also figuring out how to deal with the same issue as yours, and I do confirm lot of the docs and blogposts out there use the config struture you posted. However when I went back to the v6.1 documentation of the bundle I found this:

Dynamic templates

Dynamic templates allow to define mapping templates that will be applied when dynamic introduction of fields / objects happens.

Documentation

fos_elastica:
    indexes:
        user:
            dynamic_templates:
                my_template_1:
                    match: apples_*
                    mapping:
                        type: float
                my_template_2:
                    match: *
                    match_mapping_type: text
                    mapping:
                        type: keyword
            properties:
                username: { type: text }

So in your case a working config would look like:

#app/config/config.yml
fos_elastica:
  clients:
    default: { host: localhost, port: 9200 }

  indexes:
    user:
      settings:
        analysis:
          analyzer:
            fr:
              tokenizer: standard
              filter: [ lowercase, stop_fr, snowball_fr ]
            autocomplete:
              type: custom
              tokenizer: whitespace
              filter: [ lowercase, engram, elision ]
            csv:
              type: pattern
              pattern: '\s*,\s*'
              lowercase: false
          filter:
            snowball_fr:
              type: "snowball"
              language: "French"
            stop_fr:
              type: "stop"
              stopwords: "_french_"
            engram:
              type: edge_ngram
              min_gram: 2
              max_gram: 15
      properties:
        username: ~
        email: ~
        organization:
          type: object
          properties:
            id: { index: true }
            code: { index: true }
            name:
              index: true
              type: text
              fields:
                source: { type: text, index: true }
      persistence:
        driver: orm # orm, mongodb, propel are available
        model: App\Entity\User
        provider: ~
        listener: ~
        finder: ~
