So the release script builds like this:

./mvnw -Pdocbook,documentation-pdf,dist,perf,relocation,release clean deploy -DskipTests=true -Dcheckstyle.skip=true -DperformRelease=true -Dmaven.compiler.useIncrementalCompilation=false

See https://github.com/hibernate/hibernate-noorm-release-scripts/blob/master/deploy.sh#LL23C45-L23C45

Maybe that command doesn’t produce the right documentation?

Another lead: the release script retrieves the documentation from the dist , see https://github.com/hibernate/hibernate-noorm-release-scripts/blob/3c3391160c29fcd38ffae61a15172c58948dd02d/upload-documentation.sh#L29 .

Maybe the documentation in the dist zip is incomplete?

Marko Bekhta , could you please investigate?

You can find the logs of the release here, if necessary: https://ci.hibernate.org/blue/rest/organizations/jenkins/pipelines/hibernate-search-release/branches/main/runs/8/nodes/23/steps/43/log/?start=0
