Is there any way to highlight multiple searches in (g)Vim?

Question

I want to search for multiple strings in Vim/gVim and have them highlighted in different colours. Is there a way of doing this with out-the-box Vim or with a plug-in?

Answer 1

For searching multiple strings in vim you can do like:

/search1\|search2

This works, and will highlight both search1 and search2, but with same color. You have to do this in vim editor.
