How to make a request in Rails for a selection of materials that have a lot of text?

Question

MySQL

There is a model that has a text field. How to correctly get all models for which this field contains more text than, for example, 100 characters?
I imagine it something like this (but it's wrong):
$reviews = Review.where(text > 100).all

Answer 1

something like this
dev.mysql.com/doc/refman/5.7/en/string-functions.h...
$reviews = Review.where("LENGTH(text) > 100").all
