I just upgraded to Elastic Search 1.5.0, and so far I can’t make inner_hits work with a nested filter, although it works fine with a nested query.
Suppose I want to extract an internal subject inside a movie object.
When I run the following subquery :
Syntax 1
GET my_index/movie/_search { "query": { "filtered": { "query": {"match_all": {}}, "filter": { "nested": { "path": "actors", "query": { "match": { "actors.id": 12345 } }, "inner_hits" : {} } } } } }
=> I get inner_hits as documented here , which is very good.
But when I try to execute an equivalent query with a nested filter :
Syntax 2
GET my_index/movie/_search { "query": { "filtered": { "query": {"match_all": {}}, "filter": { "nested": { "path": "actors", "filter": { "term": { "actors.id": 12345 } }, "inner_hits" : {} } } } } }
=> I get the following parsing error
QueryParsingException [[my_index] [nested] requires either a query or a filter field]
(and this last request works fine when I delete inner_hits - except that I don't get inner images ...)
Is there something wrong with the syntax I'm using, or is inner_face not yet implemented with a filter attached?
Thanks in advance

It works with the syntax below @mdewit (thanks!)
Syntax 3
GET my_index/movie/_search { "query": { "nested": { "path": "actors", "query": { "filtered": { "filter": { "term": {"actors.id": 12345} } } }, "inner_hits" : {} } } }
although this syntax does not match the nested doc filter
=> I still do not understand what is wrong with syntax 2. It seems to me that the ES error is for me.
Edit 04-22-2015: bug fixed in ES 1.5.1, see my comment below
