search ignores properties that are not configured as hidden

[KonradHoeffner]

In ols-config.yaml I have not set any value for "hidden_property". The search index is generated as part of the general Docker setup, all volumes have been cleared with "docker compose down -v" before "docker compose up" and it has been built too. I thus assume that all properties of my ontology are included in the search index. However in practice, several of my properties are just ignored by the search:

    <owl:Class rdf:about="https://ols.imise.uni-leipzig.de/ontologies/anno#Eminence">
        <rdfs:subClassOf rdf:resource="https://ols.imise.uni-leipzig.de/ontologies/anno#Elevation"/>
        <rdfs:comment>Standring (2016): less often applied to certain bony projections;

    </owl:Class>

For example, I get 0 results for the term "Standring", which is included both in "rdfs:comment" and in "kind_of_association".

P.S.: Search in synonyms (configured as skos:altLabel) does not work as well.

Looking into the SOLR index, the synonyms and comments are not indexed at all:
