Searching by Size - can this be done?

I also "think" that's the case, but since PC's documentation always differentiates between products and sub-products, I thought it best to double check.  Really crossing my fingers as this will be a HUGE improvement.

Not through the custom search fields, which would be set at the Parent Product level. However, this is an interesting search feature as well and a separate widget could be developed to allow for this. We'll look into it when we have time, but I honestly doubt that this would happen before the release of version 3.5

The challenge here is definitely performance. It's definitely not easy to implement as it might appear as searching the database in real time (querying all sub-products) to come up with correct real time values is not an option. It would create a huge performance issue on stores with thousands of sub-products. On the other side, if you don't do a real-time check, you could end up with a very large number of options to choose from, many of which could lead to empty searches.
