I’m creating a javascript regex to match queries in a search engine string. I am having a problem with alternation. I have the following regex:
.*baidu.com.*[/?].*wd{1}=
I want to be able to match strings that have the string ‘word’ or ‘qw’ in addition to ‘wd’, but everything I try is unsuccessful. I thought I would be able to do something like the following:
.*baidu.com.*[/?].*[wd|word|qw]{1}=
but it does not seem to work.
replace
[wd|word|qw]with(wd|word|qw)or(?:wd|word|qw).[]denotes character sets,()denotes logical groupings.
