Elasticsearch _validate API fails queries that _search API allows -

i’m trying use _validate api , rejects invalid queries exact body submitted works when sent _search api. _validate request body need different in way?

for “explain” result things “no query registered [fields]". removing return fields list, complains filter.

here example:

curl -s -xget 'http://localhost:9200/4af9aae4-7ec1-458d-8c50-692ddb0f2c6d/msg,file,file-info/_validate/query?explain=true' -d '{"fields":["id"],"filter":{"not":{"and":[{"numeric_range":{"msg-size":{"gte":1000}}},{"query":{"prefix":{"content-type.verbatim":"application/"}}}]}}}' | python -mjson.tool {     "_shards": {         "failed": 0,          "successful": 1,          "total": 1     },      "explanations": [         {             "error": "org.elasticsearch.index.query.queryparsingexception: [4af9aae4-7ec1-458d-8c50-692ddb0f2c6d-0] request not support [fields]",              "index": "4af9aae4-7ec1-458d-8c50-692ddb0f2c6d-0",              "valid": false         }     ],      "valid": false } 

removing fields, reports query not support filter

curl -s -xget 'http://localhost:9200/4af9aae4-7ec1-458d-8c50-692ddb0f2c6d/msg,file,file-info/_validate/query?explain=true' -d '{"filter":{"not":{"and":[{"numeric_range":{"msg-size":{"gte":1000}}},{"query":{"prefix":{"content-type.verbatim":"application/"}}}]}}}' | python -mjson.tool {     "_shards": {         "failed": 0,          "successful": 1,          "total": 1     },      "explanations": [         {             "error": "org.elasticsearch.index.query.queryparsingexception: [4af9aae4-7ec1-458d-8c50-692ddb0f2c6d-0] request not support [filter]",              "index": "4af9aae4-7ec1-458d-8c50-692ddb0f2c6d-0",              "valid": false         }     ],      "valid": false } 

some queries work validate api, it's not across-the-board failure.

my understanding _validate runs same syntax checks etc when actually execute query, not sure going on.

other details:

elasticsearch v 1.2.1 ubuntu linux precise 64

you need wrap query in query key use _validate endpoint - that's why last example working first 2 not.

note

the query being sent in body must nested in query key, same search api works [1.0.0.rc1] added in 1.0.0.rc1. query top-level object..
