find was added in 0.17.0, you'll need to update your local version.

Thank you for your reply. In addition, I have 40000 pieces of data. I want to judge whether a field is in it. If it is, it will be filtered. What should I do in VRL?

[spencergilbert]

There are a number of "lookup" functions here depending on the type of data being used.

well,Thank you for your reply.
