There are several reasons why you may not be able to open a search from a Dashboard.
- If you don't own a Dashboard, you may not be able to open a search query from a Dashboard by using Show in Search.
- Or it may be that the original Dashboard Link has been changed to drill down to another Dashboard, instead of showing the query in the Search page. How would you know? This can be confusing when you just want to view the query and the messages it returns in the Search page.
To workaround these issues, you can always make a copy of the Dashboard from the Library. Then you can edit the copy as you like, because you own the copy. For instructions, see Copy Contents in the Library.
