Determine if any elasticsearch entries are missing the "paths" field

Swarm 15 introduced the setting search.enableDelimiterPaths=True, so that any search feeds created will have a new paths field which allows for faster delimiter listings when gateway.cfg has [folder_listings] usePaths=true (https://perifery.atlassian.net/wiki/spaces/public/pages/2443810201/Gateway+Configuration#%5Bfolder_listings%5D ).

Gateway will log a warning if it cannot take effect because some elasticsearch entries are missing the field. This can happen if the search feed was created before that setting or if the setting was temporarily changed to False while adding/updating objects.

You must have access to the elasticsearch endpoint, which should only be available on the internal storage network.

1. Choose an elasticesarch node name or ip from the Search Feed.

2. Note the cluster.name and search feed number (the first is 0).

3. Issue this curl:

   curl -H 'Content-type: application/json' 'ELASTICSEARCH-HOST:9200/index_CLUSTER-NAME0/_search?pretty&size=100' --data-binary '
   {
     "query": {
       "bool": {
         "must": {
           "terms": {
             "stype": [
               "NAMED"
             ]
           }
         },
         "must_not": {
           "exists": {
             "field": "paths.p1"
           }
         }
       }
     }
   }

4. The resulting entries are at least some of the entries preventing the use of usePaths=true.
