Searching calendar events in Thunderbird used to search both title and description fields. For example, if I searched for "dental" it would find events titled "Dental appointment" and also events with "dental" somewhere in the description field. Now it only seems to search the title. I've always put most of the information in the description field, and I use the calendar primarily as a diary record of my life and things I need to keep track of, so this is a major downgrade in terms of usability for me. Is there any way to still search the description field?
