  ]
end

Documentation is available on HexDocs and may also be generated with ExDoc.

Usage

You may install ParadeDB via Docker, or by loading the extensions into an existing Postgres database.

Create lib/postgrex_types.ex with the contents below. You may omit Pgvector.extensions() if you aren't working with vectors:

Postgrex.Types.define(
  ParadexApp.PostgrexTypes,
  Pgvector.extensions() ++ Paradex.extensions() ++ Ecto.Adapters.Postgres.extensions(),
  []
)

Add the following to config/config.exs:

config :my_app, MyApp.Repo, types: MyApp.PostgrexTypes

Create your Ecto schema and a search index in your migrations.

Once complete, you're ready to run search queries:

import Ecto.Query
import Paradex

alias MyApp.Call
alias MyApp.Repo

from(
  c in Call,
  where: c.transcript ~> "bus"
)
|> Repo.all()

More examples are available in the API docs.
