Query using a wildcard not working with icu_collation filter

Hello everyone

for my work I need to create an index which uses unicode collation algorithm, but we discovered that wildcard queries are not working.

One of the first tests were tried to switch text fields from our analyzer to standard, and it worked. I read many times the docs and I don't know if I'm doing something wrong, is a limitation or a bug...

Also I queried the _validate/query endpoint to check there's something wrong but I didn't seen anything strange.

I've uploaded a bash script to my gist account which recreates my problem

icu_test.sh

#!/bin/bash

echo "==== Creating index ===="
curl -XPUT 'http://localhost:9200/icu_wildcard/?pretty=1' -d '{
    "settings" : {
        "index" : {
            "number_of_shards" : 1,
            "number_of_replicas" : 1
        },
        "analysis" : {

Thanks in advance.

PD: I'm using elasticsearch version 2.1.1
