There is used to be a lovely fansite that can search up parts of characters names. I want to let you know that this search option has some trouble with special characters like - or '. For example, I have a friend named Shadow'Raider and when I type Shadow'Raider nothing appeared characters' names will appear. I'm called Tibia Royal:

All you do is you type in Banana for example in the search bar press enter then select where it says characters and a whole bunch of Royal but once I typed Shadow Raider her name did appear as Shadow'Raider. Here's the link to the fansite it's this fansite is not sure how accurate it is. However, I think it doesn't work for all characters I can't search active and the links no longer work. But, I have another character that's also hidden that is searchable so I cannot attest to this search working for all characters.When I find a better website I will edit my character named Nitasha, I unhid her to see if that will post.
