Hi all,

my suggestion mapping and my suggestion call is working in principle,  
except the behaviour that should be enabled by the  
preserve\_position\_increments: false flag.

Excerpt of the ES reference:  
"preserve\_position\_increments Enables position increments, defaults to true.  
If disabled and using stopwords analyzer, you could get a field starting  
with The Beatles, if you suggest for b. _Note_: You could also achieve this  
by indexing two inputs, Beatles and The Beatles, no need to change a simple  
analyzer, if you are able to enrich your data."

my mapping:

```
                    "suggest": {
                         "type": "completion",
                        "index_analyzer": "standard",
                        "search_analyzer": "standard",
                        "payloads": true,
                        "preserve_separators": false,
                        "preserve_position_increments": false,
                        "max_input_length": 250
                    }

```

that is my call:

POST [http://localhost:9200/](http://localhost:9200/)/\_suggest {  
"test-suggest" : {  
"text" : "Adlon",  
"completion" : {  
"field" : "persons.3.perLanguage.deu.suggest"  
}  
}  
}

the value of the field above is: Percy Adlon

it is working for the Text Percy, Per or PercyA

Any ideas what I am doing wrong? (ES version 1.3.2)
