I have tried several times to us the Search engine on this Board.
What am I doing wrong?

You aren't doing anything wrong. It's not working.

If it was today, probably nothing. The board appeared to be having problems. Try again tomorrow.

This is another post noting that search is not working. I sent Admin a message. There was some down time on the board today.

The new owners are still trying to work things out! soon we hope it will be back to normal!
