ERR failed to remove item from index error="entity not found" ... service=search

[ebin-dev]

If a file is deleted either on the client, or on the server using the web interface, OpenCloud outputs the following error message:

2026-01-27T16:05:52.150874+01:00 grid opencloud[6734]: 2026-01-27T16:05:52+01:00 ERR failed to remove item from index error="entity not found" Id={"opaque_id":"9755ea9b-cccc-4ec5-8631-df60cb5c7f67","space_id":"ad08d4f1-0c1b-4a14-a026-c4f4bb3b2deb","storage_id":"741ef4f5-9d65-4c6b-a9e7-2652bd274222"} service=search

This behavior is reproducible and occurs with OpenCloud 4.0.1 and 5.0.0. I am using OpenCloud bare metal and decomposedfs.

Steps to reproduce

1. Create a file in OpenCloud (on the client or via the web interface)
2. Delete the file (on the client or via the web interface)
3. The error 'ERR failed to remove item from index error="entity not found" ... service=search' is thrown by OpenCloud
