NextCloud: Is anyone actually using FullTextSearch (Elastic Search)?

my 50 cts: Nextcloud: ElasticSearch: Memory usage and ParamsModel::Incomplete line

Otherwise I have the same symptoms as you do. Additionally the mysterious file locks: NextCloud: Filelock
I think that an integrated full text search is essential for such a system and I am surprised that the NC guys pay so little attention to it.

Sincerely, Marko
