Example - Cleaning up an extracted username
Consider the following document:
We want to extract the username from this string, so that we can search and query it directly. This can be done using the extract
keyword with a regular expression.
This results in this log object:
Notice the trailing space at the end of the username. This is because a stray space has made its way in. We can use rtrim
to clean this up:
This will remove the trailing space from the username and result in a cleaner value.
