PS:
Regarding search terms, I often gave advices regarding the following on
Ubuntu flavour mailing lists:
http://www.letmegooglethat.com/?q=jackd
http://www.letmegooglethat.com/?q=linux+jackd
Sometimes there is no big difference between keywords e.g. within
quotes or separated words and sometimes there is:
http://www.letmegooglethat.com/?q=hello+kitty
http://www.letmegooglethat.com/?q=%22hello+kitty%22
http://www.letmegooglethat.com/?q=sauer+lustig+ern%C3%A4hrung
http://www.letmegooglethat.com/?q=%22sauer+lustig+ern%C3%A4hrung%22
Not only the hidden algorithms of a search engine and the user's skills
how to use a search engine are important. Popularity usually is a major
criterion!
