My b2evolution Version: 1.9.x

Hi,

I was wondering if there are already some build in possibilities / or if it could be done with simple hacks to change the standard order of search hits... at least by adding "something" to the URL by hand. I intend to implement a search-URL with a predifenied keyword in my sidebar for a subject, for which I have no separate category. Simply one... but for this, and at the moment this only, I would like to turn around the order of shown posts, so that the oldest one is at the top?

Is this possible and when yes... how?

Many thanks in advance,
Daniel
