I have the following in a text file:
This is some text for cv_1 for example
This is some text for cv_001 for example
This is some text for cv_15 for example
I am trying to use regex cv_.*?\s to match cv_1, cv_001, cv_15 in the text. I know that the regex works. However, it doesn't match anything when I try it in Vim.
Do we need to do something special in Vim?

Vim's regexes are most similar to Perl's, in terms of what you can do. The difference between them is mostly just notation; If you want a better (more serious) explanation, look up "Traditional NFA" in Mastering Regular Expressions.
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.
^ * $ \ ? ) have special significance to the search process and must be “escaped” when they are used in a search. To escape a special character, precede it with a backslash ( \ ). For example, to search for the string “anything?” type /anything\? and press Return.
The simplest way to perform a search and replace in Vim editor is using the slash and dot method. We can use the slash to search for a word, and then use the dot to replace it. This will highlight the first occurrence of the word “article”, and we can press the Enter key to jump to it.
The non-greedy character ? doesn't work in Vim; you should use:
cv_.\{-}\s
...instead of:
cv_.*?\s
Here's a quick reference for matching:
* (0 or more) greedy matching
\+ (1 or more) greedy matching
\{-} (0 or more) non-greedy matching
\{-n,} (at least n) non-greedy matching
