While this is only from my personal experience, I tend to wrap my
pattern in /.../ if it's anything beyond a simple single word. So I
might do

:vimgrep foobar *.c *.h

whereas I'd use

:vimgrep /foo.*bar/ *.c " uses a regexp
:vimgrep /foo bar/ *.c " has a space
:vimgrep /@term@/ *.c " has the same char at the beginning/end

I'm pretty sure (shooting from the hip here, so test to make sure)
that as long as it doesn't have a space in it and it doesn't have
the same non-word character at the start and end of the pattern, it
should be fine to omit them. But rather than think, I just use the
heuristic of "if it's a single word, don't bother; otherwise, wrap
the pattern"
