Search in VIM (grep and find). Search the entire project, except for folders

Question

vim

I need to go through all the files in the current folder, except for the files in folder1 and folder2, and find the word 'word' in them.
How can I do this?
Why doesn't it work? How to find "everything except ..." in find?

:grep 'word' `find . ! \( -name '*folder1*' -o -name "*folder2*" -a -type d \)`

Thank you!

Answer 1

:grep -r "word" . --exclude-dir={folder1,folder2}
