Function related to Orange GUI

i am a new beginner to Orange GUI data mining software and i have some question related to that.

First, i would like to know if there is any search function so i can search if the column contain a specific word.

Second, if orange have any function for Dimension reduction?

Best Regards

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.
