Windows Search on Vista vs on XP

I have three computers (i7 920 with Vista, Lenovo S10 netbook with XP Home and IBM Laptop R40 with XP Pro) and I've noticed a difference between how the two versions of Windows Search works. I've installed the corresponding versions on my desktop (i7, Vista) and my laptops.

I've installed 5 years worth of e-mails on all systems (don't ask...) as imported storage folders and the Vista version searches all e-mail folders, past and present, just what I wanted (text and subject lines).

The XP version also does a complete search but displays the file name instead of the subject line of the e-mail.

Question: since the Vista version figured out how to display the subject line using the same source files, is there a way to get the XP version to also display the subject line of an e-mail instead of the file name? It currently displays something like 0A4D3E15-00000465.eml instead of the subject line of the e-mail.

Well, I got around the problem. If you search using the search pane in Windows Live Mail instead of Window Search, then the subject lines of the e-mails are displayed instead properly. However, I had multiple folders of past e-mails and doing a search on each one separately was a pain. I found I could just copy and paste all past e-mails into one folder, redo the index and I can search on just two folders: the current active one and the one with all the past e-mails. Both show search results with the subject line of the e-mails displayed (Windows Search does not display the subject lines in XP, it does in Vista). You must have Windows Search installed for searching within the text of a message, otherwise you just get a subject line search.

When Windows 7 comes out I'll certainly switch all computers over.
