Your question makes no sense.  You can not have arguments (?topic=N) in file
names.  By default it saves those files in the form indexABCD.html where ABCD
is a hex hash of the entire url. (Any duplicates are named indexABCD-N.html)

User defined defined structure allows better on disk naming, such as
index-topic_N.html

Links to mirrored files are automatically converted to the local filename and
can be either:
href="html\indexABCD.html?topic=N" or:
href="html\indexABCD.html" options -> Build -> Hide query strings.
