Is there a method of matching multiple words at once in a vim search-and-replace? Something like:
:%s/foo|bar//g
to search for foo or bar and replace with nothing (this searches for the pattern foo|bar, which isn't what I want). I can search for multiple characters this way:
abcdef
:%s/[ace]//g
results in:
bdf
Can I do the same thing with words?
I'm well aware I could do this like this:
:%s/foo//g
:%s/bar//g
I'm looking for a one-line solution, if such a thing exists.

In normal mode, press / to start a search, then type the pattern ( \<i\> ), then press Enter. If you have an example of the word you want to find on screen, you do not need to enter a search pattern. Simply move the cursor anywhere within the word, then press * to search for the next occurrence of that whole word.
It means "Match zero or one of the group preceding this question mark." It can also be interpreted as the part preceding the question mark is optional. In above example '?' indicates that the two digits preceding it are optional. They may not occur or occur at the most once.
Vim has several regex modes, one of which is very magic that's very similar to traditional regex. Just put \v in the front and you won't have to escape as much.
Matching a Single Character Using RegexThe matched character can be an alphabet, a number or, any special character. To create more meaningful patterns, we can combine the dot character with other regular expression constructs. Matches only a single character.
In vim regexes, the alternation operator needs to be escaped with a backslash: use foo\|bar.

Instead of escaping | with a backslash, you can use vim's "very magic" mode with the \v sequence:
:%s/\vfoo|bar//g
