Fritz,
Welcome to the forum.
As you have found, most questions have already been answered. You just need to figure out the search terms to use to find the answers.
The search engineo n this forum is particularly basic. it returns all occurrances of each word i nthe search ,not occurrances of the phrase.
If you want to search for phrases or use boolean searches (and/or/not), use Google to search within this site (domain)

Regards,
Tony
