How to disable querying ALL fields by default

We have some users that are killing our performance because they're not putting a field in their Discover searches...rather they are just putting a single value only so elasticsearch has to search through everything.

There used to be an _all field but that was deprecated in 6.0. We're running 8.6. How do I restrict users from doing this, or at least force their queries to hit a certain field instead of every field in the index?

I'm looking into the default_field setting described here: Add default field API | Kibana Guide [8.6] | Elastic but it's not even recognizing the handler when I try it. I don't think the URI is correct.

What vesion are you on?

There is a setting you can put in the template

  "settings" : {
      "index" : {
        "query" : {
          "default_field" : ["message"]

That is the upgrade assistant... are you trying to use the upgrade assistant?

Look here


(string or array of strings) Wildcard (*) patterns matching one or more fields. The following query types search these matching fields by default:


What I showed above should work, I use it all the time.

It is even dynamic which means you can change it on existing indices!

This worked perfectly and was exactly what we needed. Thanks!
