Description Matt Jolly 2023-11-05 07:51:42 UTC 
As per this mailing list post[1], and this downstream bug[2], modern versions of Elasticsearch (>8.9.0) are not suitable for use with spotlight, failing with:


```
../../source3/rpc_server/mdssvc/mdssvc_es.c:755(mds_es_search_http_read_done)
        mds_es_search_http_read_done: json_loadb failed
```

Reported as broken against Samba 4.18.4, 4.19.2

A browse over the ES changelogs doesn't indicate any intentional changes on their end that would result in breakage, but I haven't attached a debugger or really looked at the code to work out what's wrong here.

In a log with level 10 I see:

[2023/11/27 12:16:33, 10, pid=718906, effective(0, 0), real(0, 0), class=rpc_srv] ../../source3/rpc_server/mdssvc/mdssvc_es.c:721(mds_es_search_http_read_done)
  mds_es_search_http_read_done: Got response for search [0x562088278b30]
[2023/11/27 12:16:33, 10, pid=718906, effective(0, 0), real(0, 0), class=rpc_srv] ../../source3/rpc_server/mdssvc/mdssvc_es.c:745(mds_es_search_http_read_done)
  mds_es_search_http_read_done: JSON response:
  (null)

So it seems ES sends an empty HTTP response.

Needs closer investigation...
