About this widget

The SearchBox is used to perform a text-based query.

To add a SearchBox to your search experience, use these components:

Searcher: The Searcher that handles your searches.
SearchBoxViewModel: The business logic that handles new search inputs.
SearchBoxView: The view that handles the input.

Examples

Copy
class MyActivity : AppCompatActivity() {
    val searcher = HitsSearcher(
        applicationID = ApplicationID("YourApplicationID"),
        apiKey = APIKey("YourSearchOnlyAPIKey"),
        indexName = IndexName("YourIndexName")
    )
    val searchBox = SearchBoxConnector(searcher)
    val connection = ConnectionHandler(searchBox)

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        val searchView = SearchView(this)
        val view: SearchBoxView = SearchBoxViewAppCompat(searchView)
        connection += searchBox.connectView(view)
        searcher.searchAsync()
    }

    override fun onDestroy() {
        super.onDestroy()
        connection.disconnect()
        searcher.cancel()
    }
}

Compose UI

InstantSearch provides the SearchBox composable, which you can embed in your views. It uses SearchBoxState as a state model, which is an implementation of the SearchBoxView interface. You need to connect SearchBoxState to the SearchBoxConnector or SearchBoxViewModel like any other SearchBoxView implementation.

Copy
class MyActivity : AppCompatActivity() {
    val searcher = HitsSearcher(
        applicationID = ApplicationID("YourApplicationID"),
        apiKey = APIKey("YourSearchOnlyAPIKey"),
        indexName = IndexName("YourIndexName")
    )
    val searchBoxState = SearchBoxState()
    val searchBox = SearchBoxConnector(searcher)
    val connections = ConnectionHandler(searchBox)

    init {
        connections += searchBox.connectView(searchBoxState)
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            SearchBox(searchBoxState = searchBoxState)
        }
        searcher.searchAsync()
    }

    override fun onDestroy() {
        super.onDestroy()
        connections.disconnect()
        searcher.cancel()
    }
}

If you want to create a custom Compose UI view that handles the query input, you can directly use the SearchBoxState as a state model. It provides the query property along with the setText function to streamline the design process of your custom Compose UI view.
