I have this document in my elastic DB.I am using this package
https://www.npmjs.com/package/@elastic/elasticsearch

I am searching on title.

I am doing like this.

const result= await client.search({
      index: 'products',
      "query": {
        "bool": {
          "should": [
            {
              "wildcard": { "title": "*" + search + "*" }
            }
          ],
          "minimum_should_match": 1
        }
      }
