getAlgoliaResults

Retrieve Algolia results from one or several indices with autocomplete-preset-algolia.

The getAlgoliaResults function lets you query one or several Algolia indices.

Using getAlgoliaResults lets Autocomplete batch all queries using the same search client into a single network call, and thus minimize search unit consumption. It also works out of the box with the components exposed in templates.

If you’re using autocomplete-js, you don’t need to import the preset separately. The package includes all Algolia utilities, with the appropriate user agents and virtual DOM support.

Installation

First, you need to install the preset.

npm

npm install @algolia/autocomplete-preset-algolia

Then import it in your project:

JavaScript

import { getAlgoliaResults } from "@algolia/autocomplete-preset-algolia";

If you don’t use a package manager, you can use the HTML script element:

HTML

<script
  src="https://cdn.jsdelivr.net/npm/@algolia/autocomplete-preset-algolia@1.19.4/dist/umd/index.production.js"
  integrity="hqqZsgytphUhmmnnfNd/A5wjXf0y4hifZNUTpRvy0wM="
  crossorigin="anonymous"
></script>
<script>
  const { getAlgoliaResults } = window["@algolia/autocomplete-preset-algolia"];
</script>

Example

This example uses the function along with the algoliasearch API client.

JavaScript

import { liteClient as algoliasearch } from "algoliasearch/lite";
import { createAutocomplete } from "@algolia/autocomplete-core";
import { getAlgoliaResults } from "@algolia/autocomplete-preset-algolia";

const searchClient = algoliasearch(
  "latency",
  "6be0576ff61c053d5f9a3225e2a90f76",
);

const autocomplete = createAutocomplete({
  // ...
  getSources() {
    return [
      {
        sourceId: "products",
        getItems({ query }) {
          return getAlgoliaResults({
            searchClient,
            queries: [
              {
                indexName: "instant_search",
                params: {
                  query,
                  hitsPerPage: 5,
                },
              },
            ],
          });
        },
        // ...
      },
    ];
  },
});

Parameters

searchClient · SearchClient · required

The initialized Algolia search client.

queries · MultipleQueriesQuery[] · required

The queries to perform.

Show MultipleQueriesQuery properties

MultipleQueriesQuery.indexName · string · required

The index name to search into.

MultipleQueriesQuery.query · string

The query to search for.

MultipleQueriesQuery.params · SearchParameters

Algolia search parameters.

These are the default search parameters. You can leave them as is and specify other parameters, or override them.

JSON

  "hitsPerPage": 5,
  "highlightPreTag": "__aa-highlight__",
  "highlightPostTag": "__/aa-highlight__"
}

MultipleQueriesQuery.transformResponse · function

Type definition

(response: {
  results: Array<SearchResponse<THit> | SearchForFacetValuesResponse>,
  hits: MaybeArray<Hit<THit>[]>,
  facetHits: MaybeArray<FacetHit[]>,
}) => MaybeArray<Hit<THit>[] | FacetHit[]>

The function to transform the Algolia response before passing it to the Autocomplete state. You have access to the full Algolia results, as well as the pre-computed hits and facet hits. This is useful to manipulate the hits, or store data from the results in the context.

This is the default implementation:

JavaScript

getAlgoliaResults({
  // ...
  transformResponse({ hits }) {
    return hits;
  },
});

Returns

The getAlgoliaResults function returns:

TypeScript

{
  searchClient: SearchClient;
  queries: MultipleQueriesQuery[];
  transformResponse: TransformResponse<THit>;
  execute: Execute<THit>;
}
