How can I create tags in order to retrieve my notes quickly?

The new Notes App allows you to search for Smart Notebooks and specific words: tap on the “Search” field and start typing the word you want to find. You can search your notebooks, transcribed pages, tags, dates, comments and attachments (this feature is coming soon) as well as other properties.

Tags can be added to each page and to individual Smart Notebooks. Each tag can have a color (type or select to choose) and/or a name. Names and colors facilitate the searching and grouping process on your work online.
