Adding full-text-search to Nextcloud
https://github.com/nextcloud/fulltextsearch_elasticsearch/wiki This enables one to search through text files in nextcloud, when adding OCR even PDFs and co, a far too useful feature not to provide preconfigured out of the box ;)
However, this needs elasticsearch, and I did not find helm charts that incorporate it (like you have with OnlyOffice) - so should we run a separate chart for that? https://github.com/elastic/helm-charts
There are also Dockerfiles available to combine them: https://github.com/R0Wi/elasticsearch-nextcloud-docker
