What is the search algorithm in telegramm?

Question

Information Security

It's important to keep in mind that you can't hide an account from global search if a username is set. After assigning a nickname (in the settings - “Username”), you can always later find the account itself using it. There is nothing wrong with this fact, just because the username is unique, there is a risk of being in a situation that I recently encountered. The contact specified in the channel description through the search gave out a similar person (whoever searched for a username on Skype at least once will understand me). As a result, I wrote to the wrong person, and I was deceived for money. For example, here is the original login - @Janett93, and upon request, it gives out 2 more fake contacts, this is @Janett93_channel which is a channel created by scammers. From this question, what is the contact search algorithm? and how is a fake created so that it is searched for in the search along with the original?
