In Google, without using the Advanced Search screen, the words that are not in quotes can be anywhere in the found document but will be in the document. When you put words in quotes, that exact phrase will be in the document. When you put a hyphen (minus sign) in front of a word, that word will not appear in the found documents.

If you are looking for songs by Bob Gibson (the singer/songwriter not the baseball player) you would search for

"Bob Gibson" lyrics
or
"Bob Gibson" -baseball

"Bob Gibson"
gets 20,800 hits
"Bob Gibson" lyrics
gets 624 hits
"Bob Gibson" -baseball
gets 9,950 hits

Merely excluding baseball includes the Bar BQ restaurant and a few personal home pages.

If you want songs by Bob Gibson and Phil Ochs,
"Bob Gibson" "Phil Ochs"
gets 318 hits
"Bob Gibson" "Phil Ochs" lyrics
gets 95 hits.

Does that make sense?
