# REST Suggester API
The REST Suggester API binds the 'Suggest API' to the REST Layer directly. Hence there is no need to touch the query layer for requesting suggestions.
This API extracts the Phrase Suggester API and makes 'suggestion request' top-level objects in suggestion requests. The complete API can be found in the
underlying ["Suggest Feature API"](http://www.elasticsearch.org/guide/reference/api/search/suggest.html).

# API Example
The following examples show how Suggest Actions work on the REST layer. According to this a simple request and its response will be shown.

## Suggestion Request
```json
curl -XPOST 'localhost:9200/_suggest?pretty=true' -d '{
    "text" : "Xor the Got-Jewel",
    "simple_phrase" : {
        "phrase" : {
            "analyzer" : "bigram",
            "field" : "bigram",
            "size" : 1,
            "real_word_error_likelihood" : 0.95,
            "max_errors" : 0.5,
            "gram_size" : 2
        }
    }
}'
```
This example shows how to query a suggestion for the global text 'Xor the Got-Jewel'. A 'simple phrase' suggestion is requested and
a 'direct generator' is configured to generate the candidates.

## Suggestion Response
On success the request above will reply with a response like the following:
```json
{
    "simple_phrase" : [ {
        "text" : "Xor the Got-Jewel",
        "offset" : 0,
        "length" : 17,
        "options" : [ {
            "text" : "xorr the the got got jewel",
            "score" : 3.5283546E-4
        } ]
    } ]
}
```
The 'suggest'-response contains a single 'simple phrase' which contains an 'option' in turn. This option represents a suggestion of the
queried text. It contains the corrected text and a score indicating the probability of this option to be meant.

Closes #2774
minor cleanup suggest api
- make sure we close the parser
- fail when no content is provided in the rest request
- reuse the suggest parse element
