[Typo3] indexed search: global AND sub-page searches?

[Charles Rector]

I am having problems getting the indexed search to work for a specific 
set of sub-pages when I already have searching enabled for the whole site.

I've read the documentation and I've been fiddling around with it, and 
it seems to work great if I turn on indexing in my root page and only do 
global searches, or if clear out all the phashes for searching and then 
only turn on indexing starting with one of the sub-pages. I can't seem 
to get both to work at the same time.

Here is roughly my setup:

+ Root Page (15)
	+ Global Search Page
	+ Page A
	+ Page B
	+ Page C
	+ Sub Page (24)
		+ Refined Search Page
		+ Sub Page X
		+ Sub Page Y
		+ Sub Page Z

I set the following in my Root Page typoscript:

	page.config.index_enable = 1
	page.config.index_externals = 1
	plugin.tx_indexedsearch.show.rules = 0
	plugin.tx_indexedsearch.search.rootPidList = 15

Then I set the following in my Sub Page typoscript:

	plugin.tx_indexedsearch.search.rootPidList = 24

On my Global Search Page I specify the Root Page as the startingpoint. 
On my Refined Search Page I specify Sub Page as the startingpoint.

When I do a global search, it works great. However, when I run a refined 
search, I never get any results.

Am I setting this up wrong? Any advice appreciated!
