Why does my rex not work on splunk?

[SplunkEmp22]

Hi, i don't know where is the problem. The search it's:

| rex '(?<field>H.+)\\'

| table field

I want to use regular express. for parsing field and i want to show in output the result.  The field got a path like \Pc\Hardware\Nice\ok . I want to get all of the words after Pc\. 

I don't know how to solve, he literaly does nothing and return the same origin data.

Thank u

You have to double-up on backslashes in Splunk regex - compared to something that works in regex101.com for example

| rex "(?<field>H.+)\\\\"
