Snapshot restore doesnt restore ANALYZED

Elastic Stack Elasticsearch
1

I recently restored a snapshot.
I notice the flag ANALYZED is present in the restored data.

Do I really need to re-establish that the field should be NOT ANALYZED?
Why doesn't the restore restore the data with NOT ANALYZED in tact?

No, it should come back as-is.

What version of ES was the snapshotted index created on? My suspicion is that the mapping was inconsistent before it was snapshotted and therefore you're getting back what happened to be there.

  • Elasticsearch: 2.0.0 to 2.3.1

  • Kibana: 4.0 to 4.5

  • logstash: 2.0.0 to 2.3.1

Here is the mapping I used:

curl -XPOST http://localhost:9200/member_type_history -d '{
  "mappings" : {
    "Member Type" : {
      "properties" : {
        "Member Type" : {
          "type" : "string",
          "index" : "not_analyzed"
        }
      }
    }
  }
}'
