Integrate creator search with SBH3 creator search

[danielfang97]

On SBH1, when doing creator search, the following is entered into the search bar:
dc:creator='Daniel Fang'&

However, on SBH3, we cannot use single quotes (') as this would cause a CORS error in the browser. SBH3 has implemented using <> to denote the creator's name.

For testing purposes, we will make the same change for SBH1, so that it will also use <> instead of ''.
