Hello,

I have the following mapping for address suggestion:

```auto
PUT /autocomplete
{
  "mappings": {
    "address" : {
      "properties" : {
        "city": { "type" : "string" },
        "district": { "type" : "string" },
        "street": { "type" : "string" },
        "city_suggest": {
          "type": "completion"
        },
        "district_suggest": {
          "type": "completion"
        },
        "street_suggest": {
          "type": "completion"
        }
      } 
    }
  }
}

```

The idea is to get matching cities, districts, and streets with their parents included, i.e. considering the following dataset

```auto
POST /autocomplete/address/1
{
  "city": "Kiev",
  "district": "Shevchenkovsky",
  "street": "Shevhenko",
  "city_suggest": {
    "input": ["Kiev"],
    "weight": "1"  
  },
  "district_suggest": {
      "input": ["Shevchenkovsky"],
      "output": "Kiev, Shevchenkovsky",
      "weight": 10
  },
  "street_suggest": {
      "input": ["Shevchenko"],
      "output": "Kiev, Shevchenkovsky, Shevchenko",
      "weight": 100
  }
}

POST /autocomplete/address/2
{
  "city": "Kiev",
  "district": "Shevchenkovsky",
  "street": "Pobedy ave",
   "city_suggest": {
    "input": ["Kiev"],
    "weight": "1"  
  },
  "district_suggest": {
      "input": ["Shevchenkovsky"],
      "output": "Kiev, Shevchenkovsky",
      "weight": 10
  },
  "street_suggest": {
      "input": ["Pobedy ave"],
      "output": "Kiev, Shevchenkovsky, Pobedy ave",
      "weight": 100
  }
}

```

And user input "sh" the suggestion output should be:

```auto
Kiev, Shevchenkovsky, Shevchenko
Kiev, Shevchenkovsky

```

where both district and street matches. I tried to use "bool" query as described in [https://www.elastic.co/guide/en/elasticsearch/guide/current/multi-query-strings.html](https://www.elastic.co/guide/en/elasticsearch/guide/current/multi-query-strings.html)

```auto
GET /autocomplete/_suggest
{
    "query": {
        "bool": {
            "should": {
                "match": {
                    "district_suggest": "sh",
                    "street_suggest": "sh"   
                }     
            }
        }
    }

}

```

but got an error in response

```auto
{
   "_shards": {
      "total": 5,
      "successful": 0,
      "failed": 5,
      "failures": [
         {
            "shard": 0,
            "index": "autocomplete",
            "status": "INTERNAL_SERVER_ERROR",
            "reason": {
               "type": "exception",
               "reason": "failed to execute suggest",
               "caused_by": {
                  "type": "illegal_argument_exception",
                  "reason": "Suggester[bool] not supported"
               }
            }
         }
      ]
   }
}

```

Try something like;

```auto
GET /autocomplete/_suggest
{
  "suggestion-district" : {
    "text" : "sh",
    "term" : {
      "field" : "district_suggest"
    }
  },
  "suggestion-street" : {
    "text" : "sh",
    "term" : {
      "field" : "street_suggest"
    }
  }
}

```

As per [https://www.elastic.co/guide/en/elasticsearch/reference/2.3/search-suggesters.html#search-suggesters](https://www.elastic.co/guide/en/elasticsearch/reference/2.3/search-suggesters.html#search-suggesters)

I don't think you can do multiple fields like this, you may want ngrams instead.

Thank you @warkolm,

I replaced `term` with `completion` and it worked like a charm (at least I can't see downsides ATM)!

```
GET /autocomplete/_suggest
{
  "suggest_district": {
    "text" : "sh",
    "completion" : {
      "field" : "district_suggest"
    }
  },
  "suggest_street" : {
    "text" : "sh",
    "completion" : {
      "field" : "street_suggest"
    }
  }
}

```

**RESPONSE**

```
{
   "_shards": {
      "total": 5,
      "successful": 5,
      "failed": 0
   },
   "suggest_district": [
      {
         "text": "sh",
         "offset": 0,
         "length": 2,
         "options": [
            {
               "text": "Kiev, Shevchenkovsky",
               "score": 10
            }
         ]
      }
   ],
   "suggest_street": [
      {
         "text": "sh",
         "offset": 0,
         "length": 2,
         "options": [
            {
               "text": "Kiev, Shevchenkovsky, Shevchenko",
               "score": 100
            }
         ]
      }
   ]
}

```

I will take a look at edge ngrams as well 😃
