How do I search my text items that have Hyperlinks that point to another (external) .
 

Example of a Hyperlink property
Text: CANTER v. AMERICAN INS. CO., 28 U.S. 307 (1830)
File/URL: ur://C:/Law/Case%20Law.urd?item=1116,1029,1026,1000

These Hyperlinks references are in my main database (C:\Law\JSoTA.Urd), and what I ultimately want to do is import all these Items from the external database (C:\Law\Case Law.urd) and then change the Hyperlink references in the text items to my main database (which of course would not have a .urd value becaue its local)

The URL of an internal link is not searchable within UR. If you export to RTF, Documents, or XML (including Stored Document), you could search the resulting .rtf files for such URLs.
