You can use alteration or pipe symbol to find out pattern out of several regular expression.
Pipe symbol works just like OR operator in java language.
If you want to search bikes or cars using same regex then you can separate bikes and cars token with a pipe symbol and search both of them together.
Text : Tonight Bikes and Cars are going to have a race on highway Find : Text “Bikes” and “Cars” in the same regex. ================================== Regex : Bikes|Cars
Now suppose you want to add additional regex on the search token like \b then you need to group the search using round brackets to do it Example : \b(Bikes|Cars)\b
If we had omitted the round brackets, the regex engine would have searched for a word boundary followed by Bikes, or, Cars followed by a word boundary.
