   A solution is:
   mark cards where the short name of this bg is "TheLabels"

   There are probably other ways to do it.

I don't remember the original post clearly, but if the goal is to mark cards
that contain a pattern, but only when those cards are of a particular
background, the following should be significantly faster for large stacks:

set the dontsearch of background "uninteresting 1" to true
set the dontsearch of bg "uninteresting 2" to true
  ...

mark cards by finding "gleep" in fld "glorp" -- or whatever

  ...
set the dontsearch of bg "uninteresting 2" to false
set the dontsearch of bg "uninteresting 1" to false

This takes advantage of the fact that "mark cards by finding" uses the
very speedy "find" mechanism, while "mark cards where" seems to visit every
card in the stack, regardless of the marking criteria.

As always, your mileage may vary...
