# searching
/joe/e : cursor set to End of match
/joe/e+1 : cursor set to End of match plus 1
/joe/s-2 : cursor set to Start of match minus 2
/^joe.*fred.*bill/ : normal
/^[A-J]\+/ : search for lines beginning with one or more A-J
/begin\_.*end : search over possible multiple lines
/fred\_s*joe/i : any whitespace including newline
/fred\|joe : Search for FRED OR JOE
/\([^0-9]\|^\)%.*% : Search for absence of a digit or beginning of line
/.*fred\&.*joe : Search for FRED AND JOE in any ORDER!
/\<fred\>/i : search for fred but not alfred or frederick
/\<\d\d\d\d\> : Search for exactly 4 digit numbers
/\D\d\d\d\d\D : Search for exactly 4 digit numbers
/\<\d\{4}\> : same thing
# finding empty lines
/^\n\{3} : find 3 empty lines
# Specify what you are NOT searching for (vowels)
/\c\v([^aeiou]&\a){4} : search for 4 consecutive consanants
# using rexexp memory in a search
/\(fred\).*\(joe\).*\2.*\1
# Repeating the Regexp (rather than what the Regexp finds)
/^\([^,]*,\)\{8}
# visual searching
:vmap // y/<C-R>"<CR> : search for visually highlighted text
:vmap <silent> // y/<C-R>=escape(@", '\\/.*$^~[]')<CR><CR> : with spec chars
# searching over multiple lines \_ means including newline
/<!--\_p\{-}--> : search for multiple line comments
/fred\_s*joe/i : any whitespace including newline

In regular expressions you must backslash + (match 1 or more)
In regular expressions you must backslash | (or)
In regular expressions you must backslash ( (group)
In regular expressions you must backslash { (count)
/fred\+/ : matches fred/freddy but not free
/\(fred\)\{2,3}/ : note what you have to break
