Hello!  
Recently I started studying elasticsearch(8.6.1) and got a very incomprehensible behavior.  
My index:

```auto
PUT items2/_settings
{
  "settings": {
    "analysis": {
      "filter": {
        "ru_stop": {
          "type": "stop",
          "stopwords": "_russian_"
        },
        "ru_stemmer": {
          "type": "stemmer",
          "language": "russian"
        },
        "first_synonyms": {
            "type": "synonym",
            "synonyms": ["яицо, яйцо", "курица, куриное"]
          }
      },
      "analyzer": {
        "default": {
          "tokenizer": "standard",
          "filter": [
            "lowercase",
            "ru_stop",
            "ru_stemmer",
            "first_synonyms"
          ],
          "char_filter": ["html_strip"]
        }
      },
      "mappings": {
        "properties": {
          "description": {
            "type": "text",
            "analyzer": "default"
          }
        }
      }
    }
  }
}

```

I add some test doc:

```auto
PUT /items2/_doc/14
{
    "description" : "Крылья"
}

```

This fuzzy query doesn't work:

```auto
GET /items2/_search
{
  "query": {
    "fuzzy": {
      "description": {
        "value": "Крылья",
        "fuzziness": "2",
        "max_expansions": 5,
        "prefix_length": 0,
        "transpositions": true
      }
    }
  }
}

```

But this match query with `fuzziness` is working:

```auto
GET /items2/_search
{
  "query": {
    "match": {
      "description": {
        "query": "Крылья",
        "fuzziness": "2",
        "max_expansions": 5,
        "prefix_length": 0
      }
    }
  }
}

```

What's wrong with my fuzzy query? Thank you.

Hi @pavel4008

Fuzzy query is part of the [Term Level Queries](https://www.elastic.co/guide/en/elasticsearch/reference/current/term-level-queries.html)

> Unlike [full-text queries](https://www.elastic.co/guide/en/elasticsearch/reference/current/full-text-queries.html), term-level queries do not analyze search terms. Instead, term-level queries match the exact terms stored in a field.

So, with fuzzy query your term is not analyzed by the "default" analyzer. So to occur the correspondence you would have to inform "крыл" or search in the keyword field, eg "description.keyword".
