@NightOwl888 Thanks for the detailed explanation. I'll get my first touch
to it at weekend, but I anticipate a lot of problems, since I'm only a junior
developer (e.g. I'm not even familiar with NUnit). That's why don't count on me
for now. I'll give the final answer next week.
Right now, however, I'm facing another problem. I use basic Lucene
operations (add document and search by query) in my project and it works well,
when I run the project via `dotnet run`, but when i publish the project and run
its dll, I get this error:
`fail: Microsoft.AspNetCore.Server.Kestrel[13]
Connection id "0HL0L6Q75SUEF": An unhandled exception was thrown by
the application.

Me and my team were struggling with this the whole afternoon, and then we
found this code fragment in
Lucene.Net.Core\Support\Configuration\Configuration.cs file:
`var entryAssembly = Assembly.GetEntryAssembly();
var configurationFiles = new string[0];
if (entryAssembly != null)
{
var directory = Path.GetDirectoryName(entryAssembly.Location);
configurationFiles = Directory.GetFiles(directory, "*.config");
}`
So basically, it looks at the directory, where application assembly is
located, and grabs our web.config file, and treats it as its own configuration
file. Is this correct behavior?
