PHP Snowball with French

Elastic Stack Elasticsearch
#1

Hi
I want to apply Snowball to my field "word" which is a simple word in French.
Just below are my mapping and my settings, and at the bottom it's the function I want to call to apply Snowball to my field.
It's not working, first putSettings want me to put the body field (I don't understand why), and if I add the body field I get the message ""Validation Failed: 1: no settings to update;"", just to prove me I'm not doing the right way.
What should I change to make it work ?
thanks
marc

my code that is supposed to do the job ...

$params = [
    "index" => [
         "analysis" => [
             "analyzer" => [
                 "msf_analyzer" => [
                     "tokenizer" => "standard",
                     "filter" => ["standard", "lowercase", "msf_filter"]
                 ]
             ],
             "filter" => [
                 "msf_filter" => [
                     "type" => "snowball",
                     "language" => "French"
                 ]
             ]
         ]
     ],
    'body' => []
 ];

$response = $client->indices()->putSettings($params);

The ES-PHP client is a "low level" client which closely emulates the HTTP API. Meaning the JSON that normally goes into the HTTP request body goes inside body of the PHP request. Try this instead:

$params = [
    'index' => 'my_index',
    'body' => [
         "analysis" => [
             "analyzer" => [
                 "msf_analyzer" => [
                     "tokenizer" => "standard",
                     "filter" => ["standard", "lowercase", "msf_filter"]
                 ]
             ],
             "filter" => [
                 "msf_filter" => [
                     "type" => "snowball",
                     "language" => "French"
                 ]
             ]
         ]
      ]
 ];

$response = $client->indices()->putSettings($params);

Notice how the index name goes into index, while the JSON request body goes into body.

Thanks Zachary.
It's better for the request.
I've got an exception.
Each time I had it during my previous tests, the only solution I found was to delete the index and recreate a new index with new settings. I read a solution that uses index alias to modify the index ...
Is there a simple way to apply snowball with putSettings without restarting from 0.
