Telegram supports Tags by using Hashtags which are linked an can be clicked on. When clicked, it just invokes the normal search. I mostly use it with the "Notes to myself" feature, where I can write down a quick note.

Telegram also has some form of the timeline view [1] . When tapping a date in the chat, you get a calendar in a month view. If you've sent a photo to that person on a day, that day will have a thumbnail of that photo as a background. It's a pretty hidden feature but I regularly use it to look for messages.
