Try this

your base search | rex "\"responseCode\":\"(?<response_code>\d+)"

Based on the same data, it seems your data may be json format and you can get the fields extracted automatically (or you can set that up). Is it a proper json?

Hi sravankaripe,

 | rex field=_raw "(?:.*responseCode\s?\:\s?)(?<response_code>\d+)"

Gives you a field with the name "response_code" with the specific value.

Let me know if it works and check out this great site
