In Wiki, you can search for spaces, or pages in a space, or attached files via either of 2 types:
1. Enter a keyword into the search box.
2. Select your desired page from the drop-down menu. You will be redirected to the selected page.
Note
If you are in the portal wiki, your quick search will be performed on all wiki spaces, otherwise it will only be performed on the current wiki.
The Advanced Search function allows you to search with a keyword in a specific space. This mode helps you limit the search results.
1. Enter a key term into the search box, then hit the Enter key.
The search results are displayed like the illustration below.
If no results matched with the keywords, the search screen informs "there is no search result...!"
2. Click 
to select a space from the drop-down menu to define a scale where to search for the entered word.
3. Click Search.
