Add search bar to XREF UI to filter results by name/keyword

[brrttwrks]

Journalists want to look in XREF results for a particular name quite often. While the default is OK, journalists have to paginate to look for a particular name in the XREF results without even being guaranteed that all that pagination will return a desired entity. I better approach is to add an XREF search in the UI to just search the XREF results, not unlike a document search or dataset search.
