But now I'm confused. This can not give you the error message you wrote earlier.

Whatever running something like `"wildcard": "*author*"` is one of the worst query you can run on an elasticsearch cluster. Basically you are going to run a full scan of the index which is bad.

Look at: [Wildcard query | Elasticsearch Guide [8.15] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-wildcard-query.html)

> Note that this query can be slow, as it needs to iterate over many terms. In order to prevent extremely slow wildcard queries, a wildcard term should not start with one of the wildcards \* or ?.

It would help if you provide a full recreation script as described in

It will help to better understand what you are doing.  
Please, try to keep the example as simple as possible. I mean try without nested things at first...
