Working only on some blogs

I added this to a site where I have about 100 users.

After half of the users registered, I decided by default to make the sites not indexable by search engines To do this i edited /wp-admin/install.php line 80 to $blog_public = 0; so the blogs are not public by default on install, and I also changed /wp-signup.php on line 124 so that the default for “Do you want this site ot be indexed by search engines” is “No” checked by default instead of “yes”.

Now, only some sites show up in the global search and some do not. When I edit each site alone, I can set them all to have the same kinds of permalinks, and I’ve even gone back and checked them as being “public” but for some reason, only certain ones show up in the searches and I can’t figure it out for the life of me.

Any advice would be greatly appreciated!
