If you have already used .find methods to support your repository needs you might not want to switch to QueryBuilder.

There is an easy way to implement LIKE filter using findConditions:

this.displayRepository.find({ where: "Display.name LIKE '%someString%'" });

OR for case insensitive (in postgres):

this.displayRepository.find({ where: "Display.name ILIKE '%someString%'" });

Keep in mind this is susceptible to Injection attacks, so you must protect the dynamic value explicitly.
