Within Teamwork Spaces, you can use the quick search box in the navigation bar to search your pages and content.
When you click the search box, a pane will open where you can enter your search term and view the list of results as you type.
To do a full search, including the content of your pages, select the view all results option at the bottom of the results list.
You will then see the spaces, pages, and content matching your search. The search term you entered will be highlighted in the text of the results.
Using the checkboxes, you can then filter your search results by title, content or tag.
