// v3
client := search.NewClient("ALGOLIA_APPLICATION_ID", "ALGOLIA_API_KEY")
index := client.InitIndex("ALGOLIA_INDEX_NAME")
index.Search("QUERY")

// v4
client, _ := search.NewClient("ALGOLIA_APPLICATION_ID", "ALGOLIA_API_KEY")
client.SearchSingleIndex(
    client.
        NewApiSearchSingleIndexRequest("ALGOLIA_INDEX_NAME").
        WithSearchParams(
            search.SearchParamsObjectAsSearchParams(
                search.NewEmptySearchParamsObject().SetQuery("QUERY"),
            ),
        ),
)

Wait for tasks

The wait method has been removed. Instead, use one of the following helpers:

• WaitForTask to wait until indexing operations are done
• WaitForAppTask to wait for application-level tasks
• WaitForApiKey to wait for API key operations

Copy or moving indices, settings, synonyms, or rules

Use the operationIndex method, which replaces the following methods:

• CopyIndex
• MoveIndex
• CopyRules
• CopySynonyms
• CopySettings
