You should develop your extension to work together with Typo3 caching, and
use the cHash method.

Basically the indexed search will create its index entries whenever a page
is cached. No caching - no indexed search.

The article http://typo3.org/development/articles/the-mysteries-of-chash/
will help you, the part about "binding the devils but not yourself" deals
with a similar issue as the one you have.

You will need a listing/calendar page for your events and in the listing,
the links to each individual event need to have the correct cHash so they
can be cached, and indexed, as separate content. Those links would then look
for instance something like
.. to show a certain entry.

Of course you have to make sure that your plugin is a normal USER and not
USER_INT, and does not set "no_cache" anywhere. And that caching is not
disabled anywhere else.

Also for testing it is very important not to test your page only with the
same browser session that you are logged into as BE user as otherwise there
will be no caching/indexing going on. The best solution is just to use a
different browser e.g Firefox without BE login  vs IE with bE login so you
can instantly check whether your cHash links are working.
