UI Libraries / Autocomplete / getAlgoliaResults

The getAlgoliaResults function lets you query several Algolia indices at once.

If you’re using autocomplete-js, all Algolia utilities are available directly in the package with the right user agents and the virtual DOM layer. You don’t need to import the preset separately.

Installation

First, you need to install the preset.

1
2
3
yarn add @algolia/autocomplete-preset-algolia
# or
npm install @algolia/autocomplete-preset-algolia

Then import it in your project:

1
import { getAlgoliaResults } from '@algolia/autocomplete-preset-algolia';

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

1

3
4
<script src="https://cdn.jsdelivr.net/npm/@algolia/autocomplete-preset-algolia"></script>
<script>
  const { getAlgoliaResults } = window['@algolia/autocomplete-preset-algolia'];
</script>

Example

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

import 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',
                query,
                params: {
                  hitsPerPage: 5,
                },
              },
            ],
          });
        },
        // ...
      },
    ];
  },

Parameters

searchClient
type: SearchClient
Required

The initialized Algolia search client.

queries
type: MultipleQueriesQuery[]
Required

The queries to perform.

queries ➔ queries

indexName
type: string
Required

The index name to search into.

query
type: string

The query to search for.

params
type: SearchParameters

Algolia search parameters.

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

  "hitsPerPage": 5,
  "highlightPreTag": "__aa-highlight__",
  "highlightPostTag": "__/aa-highlight__"
}
transformResponse
type: (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.

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

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