I find this quite clever in the syntax of Elixir.

There are two sets of boolean operators in Elixir and, or, not versus &&, ||, !.

The difference is that and, or, not only take literal boolean values. In contrast, &&, ||, ! can take values of all types. And all values except false and nil will evaluate to true. ⋯

Now I realize I didn't need to use a fragment. I could have used ilike.

The difference between ilike and like is that ilike is explicitly case-insensitive, whereas like could be case sensitive based on the database you are using. ⋯
