FAQ: How to use EasyCaching to query and return array of (cached) objects?

@hubert-associates Thanks for your interest in this project.

1. EasyCaching provides GetByPrefix(Async) that can use a wildcard with prefix to query some cacehd objects.
2. Using .Database to get the raw redis client instance, then you can do what you want.

Thank you for the quick answer. I was unaware of the .Database to provide the instance reference.
I looked at the src/ tests

For GetByPrefixAsync. Isn't the prefix just a REDIS pattern? It uses this I believe? But they say there "Don't use KEYS in your regular application code. If you're looking for a way to find keys in a subset of your keyspace, consider using SCAN or sets."

To use .Database. Nice. it looks like a cast does the trick here

The prefix use Redis pattern. It will use scan at first if the redis server supports this command, otherwise, it will use keys.

YES
