Tags are an awesome way to add another level of organisation and navigation to your knowledge base. A tag is a word or short phrase that "describes" the article, and an article may have as many tags as you like.
To add tags to an article - look for the "Tags" input box below the article editor, then type your tag and hit Enter after each one.
Tags you've used before will automatically come up again as you type, and you may add as many tags to an article as you like!
Tags in searches
Tags are displayed in search to give the reader additional context as to what the article is about and what it relates to. A reader can click on a tag to navigate to a list of all articles with that tag.
Clicking on a tag performs a special operation in the search that bypasses the regular search and returns a list of all articles with the same tag. You can manually perform a tag search by putting a colon in front of the tag name, like this:
Listing articles by tag
If you like, you could get really fancy and create a link that lists all articles with a certain tag. The link would look something like this, replacing "flying" with your tag.
You may also need to replace "help" with "home" if that's how your knowledge base is set up.
