Match_all with filter on percolator not working as expected

First up, I'm using Elasticsearch v1.1.1

I am getting an unexpected result from a percolator. I have broken it down
to it's simplest parts and am still getting weird results.

Firstly I create a new index with mapping:

PUT /test1
{
"mappings": {
"product": {
"properties": {
"subject": {
"type": "nested",
"properties": {
"code": {
"type": "string"
}
}
}
}
}
}
}

Then I create two objects for testing:

PUT /test1/product/12345
{
"subject": {
"code": "FA"
}
}

PUT /test1/product/12346
{
"subject": {
"code": "BA"
}
}

Then I create a query that I would expect to match on the second record
only:

GET /test1/product/_search
{
"query": {
"filtered": {
"query": {
"match_all": []
},
"filter": {
"bool": {
"must_not": [
{
"query": {
"nested": {
"path": "subject",
"query": {
"prefix": {
"subject.code": "fa"
}
}
}
}
}
]
}
}
}
}
}

So far everything is working as expected. The query returns the second
record, the first one being excluded by the filter.

I then use the same query to create a percolator:

PUT /test1/.percolator/TEST
{
"query": {
"filtered": {
"query": {
"match_all": []
},
"filter": {
"bool": {
"must_not": [
{
"query": {
"nested": {
"path": "subject",
"query": {
"prefix": {
"subject.code": "fa"
}
}
}
}
}
]
}
}
}
}
}

And test against both records:

GET /test1/product/12345/_percolate

GET /test1/product/12346/_percolate

They both return the same result:

{
"took": 1,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"total": 1,
"matches": [
{
"_index": "test1",
"_id": "TEST"
}
]
}

I have tested this without a nested object and it operates as I would
expect. At first I thought perhaps the match_all was doing something
strange to the percolator but when it wasn't a nested object it worked fine.

So my question is, am I missing something obvious? Is this expected
behaviour and I have just missed it in the documentation, or is this a bug?

I understand I could easily create this query in a different way (and am
open to some suggestions) however I am building them programatically so the
bool structure seems the best option. I have also tried using a "not"
filter with a nested "or" filter with the same result.

Should I be submitting this as a bug instead of a question?
