About this widget

<SearchBox> is a widget to let users perform a text-based query.

The search box usually is the main entry point to start the search on an InstantSearch page. You typically place it at the top of a search experience so that the user can start searching right away.

You can also create your own UI with useSearchBox().

import React from 'react';
import algoliasearch from 'algoliasearch/lite';
import { InstantSearch, SearchBox } from 'react-instantsearch-hooks-web';

const searchClient = algoliasearch('YourApplicationID', 'YourSearchOnlyAPIKey');

function App() {
  return (
    <InstantSearch indexName="instant_search" searchClient={searchClient}>
      <SearchBox />
    </InstantSearch>
  );
}

Props

placeholder
type: string
Optional

The placeholder text of the input.

1
<SearchBox placeholder="Search for products" />
queryHook
type: (query: string, search: (value: string) => void) => void
Optional

Function called every time the query changes. It takes two parameters:

  • query: The current query.
  • search: The function to trigger the search.

This prop can be useful if you need to:

  • Debounce searches to regulate requests.
  • Programmatically alter the query before sending it to Algolia.

When using this prop, you’re responsible for triggering the search with search(). If you don’t call this function, no search is triggered to Algolia.

Hook

React InstantSearch Hooks let you create your own UI for the <SearchBox> widget with useSearchBox(). Hooks provide APIs to access the widget state and interact with InstantSearch.

The useSearchBox() Hook accepts parameters and returns APIs.

Usage

First, create your React component:

import { useSearchBox } from 'react-instantsearch-hooks-web';

function CustomSearchBox(props) {
  const { query, refine, clear, isSearchStalled } = useSearchBox(props);

  return <>{/* Your JSX */}</>;
}

Then, render the widget:

<CustomSearchBox {...props} />

Parameters

Hooks accept parameters. You can pass them manually, or forward the props from your custom component.

When you provide a function to Hooks, make sure to pass a stable reference to avoid rendering endlessly (for example, with useCallback()). Objects and arrays are memoized; you don’t need to stabilize them.

queryHook
type: (query: string, hook: (value: string) => void) => void
Optional

Function called every time the query changes.

See queryHook for detail.

const queryHook = (query, search) => {
  search(query);
};

function SearchBox() {
  const searchBoxApi = useSearchBox({
    // ...
    queryHook,
  });

  return <>{/* Your JSX */}</>;
}

APIs

Hooks return APIs, such as state and functions. You can use them to build your UI and interact with React InstantSearch.

query
type: string

The query from the last search.

refine
type: (value: string) => void

Sets a new query and searches.

clear
type: () => void

Clears the query and searches.

isSearchStalled
type: boolean

Whether the search results take more than a certain time to come back from Algolia servers.

This can be configured on <InstantSearch> with the stalledSearchDelay props which defaults to 200 ms.
