        searchIndexer.Start();

        // Add some documents
        var unityDocumentIndex = searchIndexer.AddDocument("Unity Technologies");

        // Index some words
        var baseScore = 42;
        searchIndexer.AddWord("unity", baseScore, unityDocumentIndex);
        searchIndexer.AddWord("is", baseScore, unityDocumentIndex);
        searchIndexer.AddWord("awesome", baseScore, unityDocumentIndex);

        // Indicate that searchIndexer is finished indexing documents and is ready to search.
        searchIndexer.Finish();

        // Wait for the indexation to finish.
        while (!searchIndexer.IsReady())
            ;
