Searching with classification codes allows users to exploit experts' work and gain efficiency.

Patent Offices and Examiners invest a lot of time and expertise classifying patents to make their prior art searches more efficient.

Questel has been normalizing classification codes for quality assurance. However, those specific formats put a burden on users' back who have to learn them.

From now on, using those normalized proprietary classification code formats is no longer necessary, which offers users far more flexibility.
