I want to autocomplete service via Elasticsearch.I need a "did you mean" of google style. I researched very much how can I to do. I was find a fuzzy search. When I entered to "Alman", I want to Almanya only. But I received Umman too. How can I getting only "almanya"?

```
    {
        "highlight": {"fields": [{"CountryName": {"type": "plain"}}]},
        "query": {
            "bool": {
                "should": [
                    {
                        "match": {
                            "CountryName": {
                                "boost": 1,
                                "fuzziness": 5,
                                "query": "Alman"
                            }
                        }
                    },
                    {
                        "match": {
                            "CountryNameTurkish": {

Hi,

You set there fuzziness to 5. Fuzziness uses Levenshtein edit distance which measures the number of single-character edits required to transform one word in another. It has four types of one-character edits:

- Substitution of one character to another: \_f\_ox -\> \_b\_ox
- Insertion of a new character: sic -\> sic\_k\_
- Deletion of a character: b\_l\_ack -\> back
- Transposition of two adjacent characters: \_st\_ar -\> \_ts\_ar

When you set fuzziness to 5 you set the edit distance to 5, and between Alman and Umman the edit distance is 2, so fuzzy search match this word. You can set the edit distance to [AUTO](https://www.elastic.co/guide/en/elasticsearch/reference/current/common-options.html#fuzziness) and also you can set a [prefix\_length](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-fuzzy-query.html) if you think it could filter your fuzzy results.
