I can't get Yosemite to reindex Spotlight..what might i be doing wrong?

[ToddJ]

Following the instructions on a different post, I have been trying to reindex Spotlight on Yosemite. However, I am stuck now with a "Error: Unknown Indexing State" error. How can i force my iMac to start reindexing everything?

Has your spotlight been botched? IN short, finder relies on spotlight to find things quickly.

This will take a while (5 or so mins) and make your Mac go into "jump-jet" mode with the fans, but:

Drop to terminal
type in sudo rm -rf /.Spotlight-V100
then sudo rm -rf /.Spotlight-V200
then sudo mdutil -i off /
then sudo mdutil -i on /
finally sudo mdutil -E /

But it seems that I can stop the indexing, but i can't get it to restart it. Argh! if anyone has any suggestions for me to try, please let me know.

Try rebooting. While rebooting hold done CMD-OPTION-P-R and let it reboot 2 times until you hear a full volume bong.

If that doesn't work try going into system preferences, spotlight, privacy then drag your disk in there to put it on the do not index list. Then highlight it and click the minus to remove it out. It then SHOULD start reindexing. It works with an external drive, should with any other.
