Search results return files but no listing is shown

HI

I am using NC 15.0.2 with FTS 1.2.3

As you see in the picture it says 69 results returned but the file listing is empty. I tried the white theme just in case if there is an issue with this, but the same result.

I also updated the search index with

sudo -u www-data php /var/www/html/nc/occ fulltextsearch:index

curl -XGET 'localhost:9200/?pretty'                               
{
  "name" : "bLWx18j",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "y7Cm-chwRxypUlQutlPsUw",
  "version" : {
    "number" : "6.5.4",
    "build_flavor" : "default",
    "build_type" : "deb",
    "build_hash" : "d2ef93d",
    "build_date" : "2018-12-17T21:17:40.758843Z",
    "build_snapshot" : false,
    "lucene_version" : "7.5.0",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}

Any ideas or leads for me?

I got the same problem. Did you find a solution?
Also: Sometimes there are just less results returned than written on the top.
On android I don’t even get a result, it reloads multiple times, but always displays “No files here”.
