The Duplicate Content Defender ("DCD") helps prevent duplicated pages from being created.
Duplicate Content defender usage
4. Search result preview
Create a new page (or edit an existing one) and start entering a page title.
While typing, the DCD searches your Confluence instance for pages that contain the entered words in the title or content. Note: The search only considers words with at least four letters.
When it finds at least one page, it displays a list of the found pages under the page title. The found search words in the page titles are highlighted in bold.
You can click on each page title to open a preview of this page to see whether it already has the content you just wanted to create. Here, the found search words are highlighted with a yellow background.
You can also restrict the search to the current space.
When the search finds more than seven results, a "More" button is displayed to fetch the next search results.
You can close the DCD view by clicking the "Close" button.
