Where to put fuzziness or prefix_length in the request?

[AnLuoRidge]

Hi there,

Does anyone know where to put fuzziness or prefix_length in the request POST /api/:target/_search?
I failed to find the usage example in API doc. Only found some ES samples in Issues, but they are not helpful.

Following is the request I've tried/guessed. Tested it with different fuzziness and prefix_length, but it won't work.

{
    "search_type": "fuzzy",
    "query": {
        "term": "daughter",
        "prefix_length": 0,
        "fuzziness": 10
    },
    "sort_fields": ["weight"],
    "from": 0,
    "max_results": 20,
    "_source": [
       "en"
    ],
    "prefix_length": 0,
    "fuzziness": 10
}

The sentence I'm looking for is the colonel's anger at his daughter's disobedience.

I reckon I got 0 results because the distance between daughter's and daughter is 2 and the default distance is 1. I didn't place fuzziness or prefix_length in the right place.

If I search by daughters or daughter', I can get the correct result.

{
    "took": 0,
    "timed_out": false,
    "_shards": {
        "total": 3,
        "successful": 3,
        "skipped": 0,
        "failed": 0
    },
    "hits": {
        "total": {
            "value": 1
        },
        "max_score": 0.35508484912835664,
        "hits": [
            {
                "_index": "sample",
                "_type": "_doc",
                "_id": "1SIZZtGxb4A",
                "_score": 0.35508484912835664,
                "@timestamp": "2022-10-12T09:24:43.783059712Z",
                "_source": {
                    "en": "the colonel's anger at his daughter's disobedience."
                }
            }
        ]
    }
}

Thank you for your help.

You should use ElasticSearch compatible API.

Thank you! I've checked this doc in fact but there are no samples for fuzziness or prefix_length. Should I read ES's doc?

Yes, we haven't written the detail documents, you can use ES doc for it.
