Finding all numbers that are bigger than 1 in vim

/^([2-9]d*|1d+)
If we have a csv like structure

The trick here is simple, lets look at the regex from the begining:

^ – start from the begining
() – start and end of block
[] – digits within this. So we are looking from 2 to 9 to exclude the numbers begining with 1
d – search for digits
* – search for one or more
| – or operation
1 – search for numbers begining with 1
+ – containing atleast one occurence or more.
