print(res)

res= es.search(index='product_json',body={'query':{'multi_match': {'query': 'aavril'}}})

how to search the string aavril on all field ?

Answer 1

a few different ways:

using multimatch:

{
  "query": {
    "multi_match" : {
      "query":    "aavril", 
      "fields": [ "PRODUCT_NAME", "BRAND_NAME" ] 
    }
  }
}

using bool:

{
  "query": {
    "bool" : {
      "should" : [
        { "match" : { "PRODUCT_NAME" : "aavril" } },
        { "match" : { "BRAND_NAME" : "aavril" } }
      ]
    }
  }
}

or may preferred method, at index time, create a field that concatenates all the fields you want to search against and then a simple match against that field.
