    Preparing search index...

    A type that represents the various ways to provide a resource source. One and only one of the options should be provided.

    type SourceType = {
        base64: string;
        buffer: ArrayBuffer;
        external: string | FetchArgs;
        fetch: string | FetchArgs;
        file: File;
    }
    Index
    base64: string
    buffer: ArrayBuffer
    external: string | FetchArgs

    If provided, this function will be called to resolve the resource. This behaves exactly like fetch but does not internalize the results

    fetch: string | FetchArgs
    file: File
