Wildcard query over _all field on Elasticsearch 5 failed

Elastic Stack Elasticsearch
1

Hi the following query is not working anymore with ES 5.0 :

GET g_contents/_search
{
  "query": {
              "wildcard" : {
                "_all" : {
                  "wildcard" : "*doc*",
                  "boost": 1
                }
              }
            }
      }

Are they anyway to get the same result with ES 5?

First of all, that's a very bad idea. It's one of the worse query you can send to elasticsearch.
Similar to a full scan table you have in SQL databases.

Can you tell what is the error message you are getting?

Hi David,
Yes i know that's a terrible for performance but it's limited to a small index size.

the error is :

I see and I can reproduce. I'm not sure if it's expected. @jpountz WDYT? Should we open an issue?

That looks like a bug indeed!

@Benjamin_Dupre could you open an issue with all the details you sent already and link to this thread?

Thanks!
