Is it really useful in real world jobs ? Can we do things efficiently without it ?

These components are usually used in Data Quality projects.
For example, the Fuzzy Lookup can be used to match "Belgium" with "België", something the regular Lookup component can't.

Thanks. Koen. I am new so I don't know why the lookup function cannot make that distinction ?
Also, are there any other examples in which a task can be done only with fuzzy and not regular lookup ?

The lookup function is like a equi join in TSQL, it can only do exact matches.
The fuzzy lookup uses fuzzy logic to do the matching, but it uses considerably more resources.
