Hi I am using the match phrase prefix query

{  
"match" : {  
"suggestion" : {  
"query" : "lub\*",  
"type" : "phrase\_prefix",  
}  
}  
}

With this query m getting results as

{  
"name": "lube it all"  
},  
{  
"name": "assembly lubricant"  
}

I don't want assembly lubricant in the search result as it starts with assembly word,  
I want the ES to check with whole word's prefix instead of terms ,is there any way to sort this out,wild card query also giving the same result,

Do a prefix query against that field analyzed with the keyword tokenizer.  
Or do a term query against it analyzed with the edge ngram tokenizer.

Hi Nik,  
Analyzer : settings

```auto

                     "filter": [
                        "lowercase",

                  },
                  "autocomplete": {
                     "type": "custom",
                     "char_filter": [

                     "tokenizer": "standard"
                  },
                  **"keylower": {**
 **"filter": "lowercase",**
 **"tokenizer": "keyword"**
 **}**
               }

```

Mapping:

```auto
    **"suggestion": {**
 **"type": "string",**
**"copy_to": [**
 **"did_you_mean",**
 **"autocomplete",**
 **"keylower"**
**]**
 **}**

```

M using this query

```auto
{
  "prefix" : {
    "suggestion" : {
      "prefix" : "lub"
    }
  }
}

```

Still m getting the unwanted result 😕

```auto
                    "name": "air lube"
                },
                {
                    "name": "lubricant"

```

M I missing something?,is my analyzer defination is correct?,please make me correct if I am wrong.

I'm not sure! It'd be easier to figure out with the full results instead of snippets but I _think_ this is happening because you have `object` fields but you want to have `nested` subfields? I'm not 100% sure.
