Problems with MultiBlog

This is my first time using Movable Type, but it fit what we needed. A small group of 4 people will be blogging about various stuff we do, with a single blog that arrogates our blogs into one. So, I have MT 4.21-en installed. I have three blogs configured right now, blog IDs 1,2 and 3.

I have three problems. The first is that updates are not triggering on the multi blog. Second, the aggregated blogs are being sorted by author name and then created on, and not created on. The final problem is that the search feature is not working for the aggregated blogs from the first one.

1) Updates In the Multiblog "Tools>Plugins>MultiBlog 2.0>Settings" menu Content Privacy is set to "Allow" MTMultiBlog tag default arguments is set to "Exclude Blogs" with "1" Then the rebuild triggers. I have tried adding everything, and it is still not triggering

I added: When any Weblog "saves an entry/publishes an entry/comment/trackback" i have set "rebuild indexes and send pings" (basically 4 copies of the rule, with different triggers) When "blog 2/3" "saves an entry" i have set "rebuild indexes"

so i have six triggers and none of them are triggering. I post a blog entry on blog #3 and the main blog #1 does not rebuild. If i go in and manually rebuild #1 then the blog entries from #3 show up in the index of #1, but it is not auto rebuilding.

2) Sorting I want the aggregated blog entries on the index of blog #1 to be sorted by the posted date. right now it is sorted by blog source, and then posted date.

i have tried moving the sort_by on the mt:entries and there was no change.

3) search when i do a search on the main blog (#1) it only returns results from itself, not from the other blogs that i have aggregated into its index. how do I make the search global across all blogs, or at least the blogs i have aggregated.
