Cannot split a large document. InDesign CS5

Question

  Hello. I am trying to split a large document (180 pages-a book actually) into smaller documents (chapters). I tried doing it according to this thread http://forums.adobe.com/message/1321374#1321374, but when I choose the pages I want to delete, the text automatically reflows and I end up having deleted pages that I want to keep. I disabled “automatic text flow” or something, but it didn’t help. Why does that happen? Because the text frames are threaded? And what should I do? Unthread them? And how can I massively unthread them if that is the solution? Thanx a lot.

I think I got it thanks to this thread http://forums.adobe.com/message/3014839 (
I'm really late to this thread,  but you can do this manually pretty easily, too, if you want to isolate  each chapter into a new thread (though telling the chapter title style  to start on the next odd page is probably easier). Click the outport on  the last frame you want in the first thread, then click inside the frame  to break the thread. The rest of the story will be overset and the  following frames will be empty, but threaded.
Put the cursor after  the last character in the last frame and press Shift +Ctrl+End to select everything from there to the end of the story. Cut and paste into the  empty frames. Repeat for the next chapter.
Thinking about it, this might actually be all that the split story script is doing.)
