I have lots of WARN Messages in elasticsearch.log
org.apache.pdfbox.pdmodel.font.PDCIDFontType2
WARNING: Found CFF/OTF but expected embedded TTF fount Generic3-Regular
and also
POI does not currently support template.main+xml (glossary) parts. Skipping this part for now.
How to handle these warnings so I will not get them?

What version are you using? IIRC this was a problem with the attachment processor a few versions back, but it's fixed now.

Ok, this is mentioned as a known issue in the release notes for 8.6.1 here:
> **[Elasticsearch version 8.6.1 | Elasticsearch Guide \[8.9\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/release-notes-8.6.1.html#known-issues-8.6.1)**
As it says, upgrade to ≥8.7.0 to pick up the fix
