### Examples

```csharp
using System.IO;
using UnityEditor;
using UnityEditor.Search;
using UnityEngine;

static class Example_SearchIndexer_LoadBytes
{
    const string tempIndexPath = "Temp/LoadBytes.db";

    [MenuItem("Examples/SearchIndexer/LoadBytes")]
    public static void Run()
    {
        var si = new SearchIndexer("SearchIndexerExample", FileUtil.GetUniqueTempPathInProject());
        si.Start();
        var di = si.AddDocument("document 1");
        si.AddNumber("test", 2, 0, di);
        si.Finish(() =>
        {
            File.WriteAllBytes(tempIndexPath, si.SaveBytes());
            // Dispose of the SearchIndexer when you are done with it.
            si.Dispose();
            ReloadIndex();
        });
    }

    private static void ReloadIndex()
    {
        var indexBytes = File.ReadAllBytes(tempIndexPath);
        var si = new SearchIndexer("SearchIndexerExample2", FileUtil.GetUniqueTempPathInProject());

        // Load the search index from a binary stream.
        si.LoadBytes(indexBytes, (success) =>
        {
            Debug.Assert(success);
            Debug.Log($"Index loaded from {indexBytes} bytes");
            // Dispose of the SearchIndexer when you are done with it.
            si.Dispose();
        });
