Shareaza

First, I'd like to remind you that in this forum, talk about illegal downloads is not allowed, so while you may talk about searching for the name of a band, you may not talk about downloading the related content (if its legality is questionable) and I have to remind you that downloading such content is most probably illegal in the country you are living in.

As for why it is not possible searching for your search query, that's very simple: searches queries shorter than 3 letters are prohibited. So you should put ""s around your search term, to make Shareaza interpret it as a single search term, not as a group of search terms.

If you want to find what is available from AC/DC use the Wikipedia. Or iTunes or some other similar service. P2P search is really designed for queries that are much more specific than that.
