OK. Both Search and Provides now working on new site for both ab and appsbrowser.
Here is a simple fix to add to your /opt/bootlocal.sh
$ cat /opt/bootlocal.sh
#!/bin/sh
# put other system startup commands here
sed -i 's/.com/.net/' /usr/bin/search.sh
sed -i 's/.com/.net/' /usr/bin/provides.sh
As /opt/bootlocal.sh is part of your backup, A reboot and you should be good.
The new site will be obviously referenced in the next cut of microcore and tinycore.
