Filter examples by comparing to another Database

Hi everybody,
I am currently trying to learn how to use RapidMiner in order to predict the success or the failure of my database made of machines with various caracteristics.
What I am trying to do is :
- Importing one set of examples that represents the list of my machines (Name, Type, size, hardness, etc)
- Importing the choices that my user made (Size, hardness, etc)
- Filter the examples from the first database of machines thanks to the second one.
For now I tried with Filter Example but it works only with one set of example input so I woud like to know if you have some advises to do that.
Thank you very much,
Gaël.

From your description Join is the operator that you want to use as you can then set multiple keys based on the user input - Name, Type, size, hardness, etc
Things to bear in mind: if your user doesn't enter data in all variables you might want to construct your process in a clever way so that any items left blank are ignored.
One question I have is how do you want your machines filtered by user input? If your user gives a result of Hardness = Soft in one example & the second Hardness = Firm, would you want to filter to 0 machines as there are none that are both hard & soft?
