		*
		* <ul>

		*

		* <li>Removal of an existing type

		* <li>Adding a {@link AppSearchSchema.PropertyConfig#CARDINALITY_REQUIRED REQUIRED} property.

		* {@link AppSearchResult#RESULT_INVALID_SCHEMA} and a message describing the incompatibility.
		* In this case the previously set schema will remain active.

		* this case, instead of completing its future with an {@link

		* AppSearchResult#RESULT_INVALID_SCHEMA} error code, all documents which are not
		* compatible with the new schema will be deleted and the incompatible schema will be
		* applied. Incompatible types and deleted types will be set into {@link
		* SetSchemaResponse#getIncompatibleTypes()} and {@link
		* SetSchemaResponse#getDeletedTypes()}, respectively.
		* <li>Add a {@link android.app.appsearch.AppSearchSchema.Migrator} for each incompatible type
		* and make no deletion. The migrator will migrate documents from it's old schema version
		* to the new version. Migrated types will be set into both {@link
		* SetSchemaResponse#getIncompatibleTypes()} and {@link
		* SetSchemaResponse#getMigratedTypes()}. See the migration section below.

		* <p>By default, documents are visible on platform surfaces. To opt out, call {@code
		* SetSchemaRequest.Builder#setPlatformSurfaceable} with {@code surfaceable} as false. Any
		* visibility settings apply only to the schemas that are included in the {@code request}.
		* Visibility settings for a schema type do not apply or persist across {@link
		* SetSchemaRequest}s.
		*
		* <p>Migration: make non-backwards-compatible changes will delete all stored documents in old
		* schema. You can save your documents by setting {@link
		* android.app.appsearch.AppSearchSchema.Migrator} via the {@link
		* SetSchemaRequest.Builder#setMigrator} for each type you want to save.
