searching across multiple types returns doesn't find all documents matching

[billumina]

I include a bash script that recreates the situation.

#!/bin/sh

curl -XDELETE "http://localhost:9200/test"
curl -XPUT "http://localhost:9200/test"

echo

curl -XPUT "http://localhost:9200/test/foo/_mapping" -d '{
    "foo" : { 
        "properties" : {
            "id": {
                "type" : "multi_field",
                "path": "full",
                "fields" : {
                    "foo_id_in_another_field" : {"type" : "long", include_in_all:false },
                "id" : {"type" : "long"}
                   }
        }
    }
    }
}'

echo

#foo is a basically a duplicate of the foo document to support search use cases
curl -XPUT "http://localhost:9200/test/bar/_mapping" -d '{
    "bar" : {
        "properties" : {
            "id": {
                "type" : "multi_field",
                "path": "full",
                "fields" : {
                    "bar_id_in_another_field" : {"type" : "long", include_in_all:false },
                    "id" : {"type" : "long"}
                   }
                },
        "foo": {
            "properties": {
                "id": {
                    "type" : "multi_field",

                    "fields" : {
                        "foo_id_in_another_field" : {"type" : "long", include_in_all:false },
                        "id" : {"type" : "long"}
                    }
                }
            }
        }
        }
    }
}'

echo

curl -XPUT "http://localhost:9200/test/foo/1?refresh=true" -d '{
    "foo": {
                "id": 1
    }

#failure case appears even when not including the following JSON
