/**
 * @description
 * The DefaultSearchPlugin provides a full-text Product search based on the full-text searching capabilities of the
 * underlying database.
 *
 * The DefaultSearchPlugin is bundled with the `\@vendure/core` package. If you are not using an alternative search
 * plugin, then make sure this one is used, otherwise you will not be able to search products via the
 * [`search` query](/reference/graphql-api/shop/queries#search).
 *
 * :::caution
 * Note that the quality of the fulltext search capabilities varies depending on the underlying database being used. For example,
 * the MySQL & Postgres implementations will typically yield better results than the SQLite implementation.
 * :::
 *
 *
 * @example
 * ```ts
 * import { DefaultSearchPlugin, VendureConfig } from '\@vendure/core';
 *
 * export const config: VendureConfig = {
 *   // Add an instance of the plugin to the plugins array
 *   plugins: [
 *     DefaultSearchPlugin.init({
 *       indexStockStatus: true,
 *       bufferUpdates: true,
 *     }),
 *   ],
 * };
 * ```
