Although you can't search the calendar directly, you can search it indirectly by syncing your calendar with some other calendar system that does allow searching. For example, I sync my LDS.org calendar with Google Calendar. My Google Calendar then has great search capabilities, so I can easily find any text in titles or descriptions.
This certainly isn't as convenient as it would be if the LDS.org Calendar had search capabilities built in, but it's not hard at all, and I don't need to search all that often, so it works well for me.
Questions that can benefit the larger community should be asked in a public forum, not a private message.
