Incremental indexing does not delete old files in Elasticsearch

[shyyio]

          Well, it's been a while... Sorry for the unrelated report, but I tried to change the backend to Elastic Search, and now I do not have the "zero hits" issue. I have another trouble instead. If I move a file from FolderA to FolderB, after reindexing the system finds BOTH entries (with the first link naturally broken). The only way to get rid of a broken link is to do full reindexing, which takes ~2 days in my case.

I am sorry to bother, but could you please update the Docker version of the system? I managed to compile it myself, but I am getting the "failed to load magic database" error while indexing.
