Searching other than title

How can I do a search for an artist?

That is done using the folder panel.

Click the folder button top left, then set your folder panel to Creator folders.
Now use the search box top left, above the Creator folders to search.

Thank you.
Now how can I get the search to show every book the artist did?
For example, I did a search on Dan Jurgens and it just gave some of the Superman books he did. It did not show the ones he did on Warlord.

Just click his folder.
