No. There are numerous factors involved in the registration process that cannot always be predicted, so even when a search is "clear," there is no absolute guarantee that a trade mark will be registered. A trademark search is similar to a forecast; it gives you an idea of what is likely to happen, but it can be wrong at times.

A Trademark Search allows brand owners to determine whether another party has registered a similar or identical mark, which could prevent them from commercially using it on their products or services.

If a search reveals that the mark you want to use is already in use or substantially similar to one that is, you might need to think about using a different one. It's difficult to deal with this, but it's critical that you select another mark in this case.
