Or in regular expression unable to use in search

[Dinesh Babu]

Hi,
I am unable to use | in regular expression while searching two string ie (string 1|string 2)in search…does any one know why it’s not coming ??

It works fine.
For anybody to say what is going wrong for you, you’d have to present some data and a search regex.
We’re not mind-readers here.

1. in find I am giving regex as (dog | cat)
   2.opted for regular expression
   3.selecting find all in current document
   4.in search result getting 0 matches
   But dog and cat are present in my text file

Hard to tell what you are REALLY doing from that.
It appears you have extra space characters in there maybe?
Maybe you have (dog | cat) instead of (dog|cat) ?
Spaces ARE significant in regular expressions, unless you use the (?x) option in front, e.g. (?x)(dog | cat)

Anyway, alternation (the | regex operator) definitely works fine:

I dropped the wrapping parentheses for the example, but it works just as well with them as without them.
