Internal messages in Tickets

[veck]

Hi all,

I was wondering if there is a way to add internal information in a Ticket that will not be published:
A note offers the functionality, but if I perform a search on tickets, the text in a note is not retrieved.
Is there another way to add an unpublished text in a Ticket that could be retrieved in a search?
The 2 main reasons are:
-Internal documentation that is not relevant for the end-customer
-Translation of information from published messages: We support all European countries and customer like to communicate in their own language, however we like to have the questions documented in English.

I believe that we are not the only company that supports several countries/languages, I was wondering how other companies jump over this language/documentation hurdle?

Thanks
