Second, if orange have any function for Dimension reduction?

Yes, Orange has a Dimensionality Reduction Widget under the Unsupervised Learning tab. Click PCA (Principal Component Analysis)

enter image description here

As Ethan stated you can use the PCA widget to reduce the dimensions of your data.

To search internally try the select data by index widget.
