I read the documentation of  
([Query string query | Elasticsearch Guide [8.1] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html))  
and still don't understand the following example:

```
GET /_search
{
  "query": {
    "bool": {
        "must": [{
                  "query_string": {
                      "query": "1~central OR 0~park",
                      "default_field": "content"
                   }},                
                 {"query_string": {
                      "query": "park~AUTO",
                      "quote_field_suffix": ".exact", 
                      "fields": ["content"]
                    }}]
             
}}}

```

1. In the first `query_string`:  
I'm not sure I understand what is the meaning of `1~` ?  
I read about `Damerau–Levenshtein distance`, and still not sure I understand it correcly:

2. In the second `query_string`  
what is the meaing of AUTO ? (park~AUTO)
