>Does LISTSERV supports special search queries by topic,

Effectively, yes, since the Topic is required to be on the Subject: line and you
can search for a particular word or words in the Subject.  You cannot search for
'Topic: "xyz"'  You would have to search for 'Subject: contains "xyz"'

No and no.

>As I understand only subscription by topic is supported.

Yes.
