Hi,

referencing
http://www.elasticsearch.org/guide/en/elasticsearch/reference/1.x/search-suggesters-completion.html
and http://www.elasticsearch.org/guide/en/elasticsearch/reference/1.x/search-suggesters-completion.html
i tried to get suggests from middlewords without success.
Setup and Request:

#!/bin/bash

DOMAIN='127.0.0.1'
PORT='9200'
INDEX='music'
TYPE='song'

curl -X PUT $DOMAIN:$PORT/hotels -d '
{
"mappings": {
"hotel" : {
"properties" : {
"name" : { "type" : "string" },
"city" : { "type" : "string" },
"name_suggest" : {
"type" : "completion",
"index_analyzer" : "stop", # also tried standard, simple ...
"search_analyzer" : "stop", # also tried standard, simple ...

      "preserve_position_increments": false,
      "preserve_separators": false
    }
  }
}

}
}'

curl -X PUT $DOMAIN:$PORT/hotels/hotel/1 -d '
{
"name" : "Mercure Hotel Munich",
"city" : "Munich",
"name_suggest" : {
"input" : [
"Mercure Hotel Munich",
"Mercure Munich"
]
}
}'

curl -X PUT $DOMAIN:$PORT/hotels/hotel/2 -d '
{
"name" : "Hotel Monaco",
"city" : "Munich",
"name_suggest" : {
"input" : [
"Monaco Munich",
"Hotel Monaco"
]
}
}'

curl -X PUT $DOMAIN:$PORT/hotels/hotel/3 -d '
{
"name" : "Courtyard by Marriot Munich City",
"city" : "Munich",
"name_suggest" : {
"input" : [
"Courtyard by Marriot Munich City",
"Marriot Munich City"
]
}
}'

curl -XPOST $DOMAIN:$PORT/hotels/_refresh

curl -X POST $DOMAIN:$PORT/hotels/_suggest?pretty -d '
{
"hotels" : {
"text" : "Munich",
"completion" : {
"field" : "name_suggest"
}
}
}'

Response:
{
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hotels" : [ {
"text" : "Munich",
"offset" : 0,
"length" : 6,
"options" : [ ]
} ]
}

Any suggestions? Checked this against ES 1.3.2.

Thx in advance,
Tom
