Why can't I use my analyzer and get answer 'failed to find analyze'? - php

Question

I made my index with analyzer like in documentation (there).
This is my index create:
$params = [
'index' => 'mytestindex',
'body' => [
'settings' => [
'analysis' => [
'index_analyzer' => [
'my_index_analyzer' => [
'type' => 'custom',
'tokenizer' => 'standard',
'filter' => [
'lowercase',
'mynGram2'
],
],
],
'search_analyzer' => [
'my_search_analyzer' => [
'type' => 'custom',
'tokenizer' => 'standard',
'filter' => [
'standard',
'lowercase',
'mynGram2'
],
],
],
'filter' => [
'mynGram2' => [
'type' => 'nGram',
'min_gram' => 2,
'max_gram' => 20,
],
],
],
'max_ngram_diff' => 50,
],
],
];
$x = $this->obj->indices()->create($params);
Then i try use my analyzer:
$params = [
'index' => 'mytestindex',
'body' => [
'analyzer' => 'my_search_analyzer',
'text' => 'текст проверить чтобы'
],
];
$x = $this->obj->indices()->analyze($params);
But I get this message:
'{"error":{"root_cause":[{"type":"remote_transport_exception","reason":"[PEREGOVOR2][127.0.0.1:9300][indices:admin/analyze[s]]"}],"type":"illegal_argument_exception","reason":"failed
to find analyzer [my_search_analyzer]"},"status":400}'
So... what am I doing wrong? Why can't I use my analyzer and get answer 'failed to find analyze'?

You're not building your analyzer correctly. You only need one analyzer section in your settings:
$params = [
'index' => 'mytestindex',
'body' => [
'settings' => [
'analysis' => [
'analyzer' => [ <--- change this
'my_index_analyzer' => [
'type' => 'custom',
"tokenizer" => "standard",
'filter' => [
"lowercase",
"mynGram2"
],
],
'my_search_analyzer' => [
"type" => "custom",
"tokenizer" => "standard",
'filter' => [
"standard",
"lowercase",
"mynGram2"
],
],
],
'filter' => [
'mynGram2' => [
"type" => "nGram",
"min_gram" => 2,
"max_gram" => 20,
],
],
],
"max_ngram_diff" => "50",
],
],
];
$x = $this->obj->indices()->create($params);
