It depends how desperate you are:
- You can File > Export as WIX format. This is a Xara-internal version of a .WEB / .XAR file. The text is unencoded.
- You can File > Export as PDF. You are then at the whim of MS Search and your installed PDF filter.
- You can File > Export website. You can then search within the *.htm(l) files. This is unencoded.
In all cases, I would never use MS Windows Search.
My go-to search tool for this type of operation would be Notepad++ and Find in Files.
