Add custom plugins to Autocomplete

Custom plugins can help in these cases:

If you want to show a data subset differently from all matching products or articles. For example, showing all on-sale products in a separate list, or only show help articles.
You want to support searching data from other sources in your autocomplete menu.

You can add a custom plugin using the beforeAutocompleteOptions hook.

Example of sale items

This example shows how to display on-sale products in a separate list (in addition to all other results). You can achieve this by creating a source that searches into your product index, and applies a filter to only include items where the named_tags.onSale attribute is true.

JavaScript

document.addEventListener("algolia.hooks.initialize", function () {
  // Add the custom plugin to the Autocomplete.
  algoliaShopify.hooks.registerHook(
    "beforeAutocompleteOptions",
    function (options) {
      const { searchClient } = window.algoliaShopify;
      const { getAlgoliaResults } = window.algoliaShopify.externals;

      const saleItemsPlugin = {
        name: "custom-sale-items-plugin",
        getSources({ query }) {
          return [
            {
              sourceId: "saleItems",
              getItems() {
                return getAlgoliaResults({
                  searchClient,
                  queries: [
                    {
                      indexName: "shopify_products",
                      query,
                      params: {
                        filters: "named_tags.onSale:true",
                      },
                    },
                  ],
