Hi @Gaetano ,
First of all welcome to the group!
If you'd like to search for a specific keyword on a comment, you can go to the search bar in Trello and type comment:typekeywordhere.
That will show you the card where the comment appears. While the comment won't be highlighted, as a workaround, you can click on CMD+F on your keyboard to open up your browser's search bar. Then you can type in your keyword and you'll be able to find it.
You can check this article to see other search locators that can be used in Trello: http://help.trello.com/article/808-searching-for-cards-all-boards
