View Source ExTypesense.Collection (ExTypesense v0.3.5)

Module for creating, listing and deleting collections and aliases.

In Typesense, a Collection is a group of related Documents that is roughly equivalent to a table in a relational database. When we create a collection, we give it a name and describe the fields that will be indexed when a document is added to the collection.

Functions

Create collection from a map, or module name. Collection name is matched on table name if using Ecto schema by default.

Deletes a collection alias. The collection itself is not affected by this action.

Permanently drops a collection by collection name or module name.

Get a specific collection by string or module name.

Get a specific collection alias by string or module name.

Get the collection name by alias.

List all aliases and the corresponding collections that they map to.

Lists all collections.

Make changes in a collection's fields: adding, removing or updating an existing field(s). Key name is drop to indicate which field is removed (example described below). Only fields can only be updated at the moment.
