Class 'Algolia\HtmlSplitter' not found

Hi. I try integrate Algolia search with wordpress by this manual
When I try to add splitting large records, I see error “Class ‘Algolia\HtmlSplitter’ not found in /var/sites/”
Can you give me suggestion please?

Bump. Also not sure where to put this file (as seen here in the guide:

Hey ehovantsev

You need to create a file in your source code with the contents of the file class HtmlSplitter specified in

Once you have created the file, go to your functions.php, include the class to perform the split.

Let me know if is not clear, maybe we can improve the documentation.
