Well, it's your logic that takes the request from the user and executes the
search. So it's your logic that has to take care of any coordination between
threads that use the same reader. This is a standard multi-threading
resource-sharing issue.

If your application is not multi-threaded, I don't see how you can "close
the reader while the user is executing a query"...

My question is what happen when a re-opening of the reader occurs and in
the same time a user does a query on the index ? And are there solutions
for this.

Yes.  More generally, whenever there have been changes to an index
that you want your readers/searchers to see, you need to re-open the
reader/searcher.  A reader keeps a "point in time" view of the index
as of when it was open, and will not show any changes until it is
re-opened.

I don't really understand this question -- could you provide more
detail here?
