DuckDB text-expression helpers for Ecto queries.

import Ecto.Query
import QuackDB.Ecto.Text

from event in "events",
  where: contains(event.name, "duck") and starts_with(event.kind, "bird"),
  select: %{
    second_part: split_part(event.name, "-", 2),
    tags: string_split(event.tags, ",")
  }

contains_text/2 emits the same DuckDB contains(?, ?) call as contains/2. It is useful with use QuackDB.Ecto, where shared contains/2 may dispatch between text and spatial predicates.
