Query a point within a polygon

First, I would like to thank you for creating such a powerful module like geo. I'm the one who got a lot of benefits from your module and I'm truly appreciated.

In my website, I want to query a point that lies within a polygon, so I have 2 geospatial data fields on 2 different content types, one is a point and the other is a polygon. This maybe a naive topic but I can't find a way to make a relationship between those two in views. Or is there something to do with geospatial data reference? Or I have to create custom views relationship handler? I know that there are many functions provided in the module but I don't know how to use those function with the dynamic input like the value from views argument or exposed filter.

Could you give me an explanation or some brief tutorial how to do this? Or is there any document available regarding this topic?
Thank you in advance for your advice.
