Tag search index project scope issue

[Jotschi]

If i create a tag and and tag familly, and search it by endpoint /api/v2/search/tags :

{
    "query": {
        "bool": {
            "must": [
                {
                    "query_string": {
                        "query": "name.raw: state-archive AND tagFamily.name.raw: state"
                    }
                }
            ]
        }
    }
}

i get 1 result :

{
  "data": [
    {
      "uuid": "b06a217939f14810aa217939f188106e",
      "creator": {
        "uuid": "b05b061fc9f544079b061fc9f58407ec"
      },
      "created": "2019-09-11T09:01:54.051Z",
      "editor": {
        "uuid": "b05b061fc9f544079b061fc9f58407ec"
      },
      "edited": "2019-09-11T09:01:54.051Z",
      "tagFamily": {
        "name": "state",
        "uuid": "068b5e47be3045138b5e47be3005136f"
      },
      "name": "state-archive",
      "permissions": {
        "create": true,
        "read": true,
        "update": true,
        "delete": true
      }
    }
  ],
  "_metainfo": {
    "currentPage": 1,
    "perPage": 10,
    "pageCount": 1,
    "totalCount": 1
  }
}

which is fine if i create another project and call sync endpoint i get two result for the same request (tag is only attached to the first project, not the second one)

 {
  "data": [
    {
      "uuid": "b06a217939f14810aa217939f188106e",
      "creator": {
        "uuid": "b05b061fc9f544079b061fc9f58407ec"
      },
      "created": "2019-09-11T09:01:54.051Z",
      "editor": {
        "uuid": "b05b061fc9f544079b061fc9f58407ec"
      },
      "edited": "2019-09-11T09:01:54.051Z",
      "tagFamily": {
        "name": "state",
        "uuid": "068b5e47be3045138b5e47be3005136f"
      },
      "name": "state-archive",
      "permissions": {
        "create": true,
        "read": true,
        "update": true,
        "delete": true
      }
    },
    {
      "uuid": "b06a217939f14810aa217939f188106e",
      "creator": {
        "uuid": "b05b061fc9f544079b061fc9f58407ec"
      },
      "created": "2019-09-11T09:01:54.051Z",
      "editor": {
        "uuid": "b05b061fc9f544079b061fc9f58407ec"
      },
      "edited": "2019-09-11T09:01:54.051Z",
      "tagFamily": {
        "name": "state",
        "uuid": "068b5e47be3045138b5e47be3005136f"
      },
      "name": "state-archive",
      "permissions": {
        "create": true,
        "read": true,
        "update": true,
        "delete": true
      }
    }
  ],
  "_metainfo": {
    "currentPage": 1,
    "perPage": 10,
    "pageCount": 1,
    "totalCount": 2
  }
}

Seems that sync is broken for tag when there is more than 1 project index twice to ES the same tag
