Autosuggest best practices

Dear community members,

I was wondering whether there is an upper limit of TUs to be used when creating autosuggest dictionaries.

As there is a minimum of 10000 TUs required to create a dictionary, is there a maximum number of TUs which, when reached, would impact the performance when using the autosuggest dictionary?

Has anyone some experience or best practice to share on large autosuggest dictionaries?

Also, from a performance perspective, is it recommended to use a single, large autosuggest dictionary or multiple, smaller dictionaries?

Thank you for your support and advices.

Regards,

Laurent
