Filter titles in advanced search are not human readable

[kevinwkeating]

I tried filtering by target organism. You can't type in "target" and find anything, you need to scroll down and find a URL to some definition of a target organism. Trying to find "role" is only marginally better because you need to select "sbol2:role" and can't search for "role" within the box. Please revise this list to make it human readable.
