ClueBot III automatically creates an archive index when archiving. ClueBot III stores the archive indexes it creates on unique pages in its user space. The archive index for the page you are archiving can be transcluded onto your Talk:YourPage/Archive index page by putting the following text in that page:
{{User:ClueBot III/Master Detailed Indices/{{NAMESPACE}}: {{BASEPAGENAME}}}}

Archive searching

If there are several archives, it is easy to If there are several archives, it is easy to search them all at once using the optional search parameter prefix. For example, suppose we want to begin a discussion about adding a security section to the Linux article. Before bringing up the topic we can do the following search: security prefix:Talk:Linux/. This will look in all the subpages of the Linux article in its Talk namespace.

The templates {{Archives}}, {{Archive box}}, and {{Talk header}} have a parameter search=yes which provides a helpful search box on the talk page to automate searching, as do independent search templates such as {{search archives}}. It is recommended that when a page is archived, such a template be put on the surviving talk page to simplify access to past discussions.

It is difficult to say exactly when a discussion "ends" and when it is continuing. Given that archived discussions are immutable, archiving a discussion effectively ends that particular discussion. When reopening a discussion is desired, links to archived discussions can be provided in the new discussion thread.
