I still can't see to get this to work. Here's a simplified version of my
page tree:
- root
	-<1>home
		-<5>page
		-<34>page
		-<40>search
		-<42>page
		-<7>page I want search to search

In the page TS of page 40, I put this:
plugin.tx_indexedsearch.search.rootPidList=7

But, when I invoke a search from page 40, it still searches all pages.
Not just page 7.

What else am I missing?
