Problems with vim, i removed it

I'm a new user in linux. The problem is that when i tried to run the VI
(or vim) text editor, i realised that it worked really different as i
remembered it used to. Example, when i try to put in mode of "insert", in
the downside doesn't appear "INSERT", or when i try to delete with the
backspace key, it doesn't delete... it moves the cursor back, and does
nothing.
So i thought that removing it and re-installing it again would work, and
removed it by:
apt-get --purge remove vim-common
But now when i try:
apt-cache search vim
it throws nothing, and now i don't know how to install it again. Any help?
thanks people
