Default setting is what it is. Just remember to set it for what you want. If it is a newish post, a week or month is fine. If in the deep dark past I use ten years. I really should not allow a 15 year search as it slows the forums. ALMOST EVERY other forum would not allow it. I keep it there as I need it from time to time.

If I allow say a maximum two year search like many forums would only allow, people would not have to worry about "avalaches" of results either.

Use of selective search terms narrows it down.

Also select the specific forum to search, or poster's alias.

As said, if people are getting NO results, they are doing it wrong.

I really should see if I can update the forums this autumn. Then people can complain about new stuff.
