Hi,

I need help in optimizing the query to increase the number of matches without affecting the accuracy.  
What are the best options to tolerate some spelling mistakes?

Thank you.

Hi Maher,

One option might be to look at a fuzzy query:  
[https://www.elastic.co/guide/en/elasticsearch/reference/5.3/query-dsl-fuzzy-query.html](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/query-dsl-fuzzy-query.html)

```auto
POST /test-fuzz/fuzztype/
{
  "message": "this is a test"
}

POST /test-fuzz/fuzztype/
{
  "message": "this is a toast"
}

POST /test-fuzz/fuzztype/
{
  "message": "this is a testing time"
}

POST /test-fuzz/fuzztype/
{
  "message": "this is a tester"
}

      }
    ]
  }
}

```

There's also the term suggester that might be of use:

Hi, you can use the phonetic-matching [https://www.elastic.co/guide/en/elasticsearch/guide/current/phonetic-matching.html](https://www.elastic.co/guide/en/elasticsearch/guide/current/phonetic-matching.html)
