UX: Add keyword etc to Primo search box like on Libweb search box

[MargaretA-UO]

The options in Primo really ought to mirror, as much as possible, what we have on the libweb home page.
I don't see configuration options for this, but Arizona https://search.lib.asu.edu/discovery/search?vid=01ASU_INST:01ASU&lang=en has the kw/au/ti dropdown in Primo, so maybe we could copy the code? Preferably at the front of the searchbox rather than at the end.
