You can do searches under three of the Timeline tabs: My Calendar, Events and Publish. All of these searches use case-insensitive full-word searches with stemming. If you enter more than one word, there is an implied OR between each word. You can precede a word with a dash (no space between the dash and the word), which negates the word (finds items that DO NOT have that word). You can also enter a phrase enclosed in quotes. All of the searches examine the title, description and URL (if any) associated with a Timeline item on the page you are on (My Calendar, Events or Publish). There is no support for wild cards.
Search: My Calendar
When you click the My Calendar tab, and enter a search, Timeline will search all of the events, deadlines and announcements on your Timeline calendar (including events and deadlines flagged as hidden or done, and announcements flagged a read). The search is not date/time limited.
When you click the Events tab, and enter a search, Timeline will search all events (including events to which you are not subscribed). The search is not date/time limited.
When you click the Publish tab, and enter a search, Timeline will search all of your posts, regardless of their current status. The search is not date/time limited.
