Various "nested" problems with elasticsearch 0.17.9 and 0.18.5 part 2

gistfile1.txt

Steps 1-3 are the same as part 1 (https://gist.github.com/1453137)

1] Create an index called "nested_test" (eg I did this from elasticsearch-head) with 5 shards and 0 replicas

(or presumably something like 
curl -XPUT 'http://localhost:9200/nested_test/' -d '
index :
    number_of_shards : 5
    number_of_replicas : 0
'
would be equivalent)

2] Create a type mapping

curl -XPUT 'http://localhost:9200/nested_test/nested/_mapping' -d '{"type1":{"properties":{"obj1":{"type":"nested"}}}}'

3] Add a test object (I'll fix the ID here for [4]'s sake)

curl -XPOST 'http://localhost:9200/nested_test/nested/Qo3xXbFMTOG273p2048sMw' -d '{"obj1":[{"name":"blue",count:4},{"name":"green",count:6}]}'

4] Deleting by _id works fine, eg

curl -XDELETE 'http://localhost:9200/nested_test/nested/Qo3xXbFMTOG273p2048sMw'

(or whatever _id is returned from [3])

Then check the index in elasticsearch head (sorry, too lazy to dig out the REST for status), and there are 0 docs

5] However deleting by query leaves orphaned nested children

curl -XPOST 'http://localhost:9200/nested_test/nested/' -d '{"obj1":[{"name":"blue",count:4},{"name":"green",count:6}]}'
(reinsert)

curl -XDELETE 'http://localhost:9200/nested_test/nested/_query' -d '{"match_all":{}}'

Checking the index shows 2 objects remaining, although querying "match_all" either using nested or normally (expectedly) returns 0 documents
