Translate metadata to field content

[J. Landman Gay]

Aha! Of course. I should have thought of that. Mark pointed out the same 
thing. (And yes, my brief test had the metadata in the third paragraph.)

I'll try his handler when I get back to my Mac. If my guess is correct, the 
search won't take any measurable time at all and the primary delay will be 
loading the htmltext into a variable.

You guys are great.
