How to add tags in a page
Tettra indexes the entire body content of every page, so tags can be added manually to pages which will get picked up in search.
How it works
Navigate to a page and type the tags you want to add under the title. This will make the page searchable for any of the tags. Once you're done, click Publish page.
Because Tettra's search indexes the entire content of the body page, your tags will return the page in your search results for that tagged search.
