Administration - Search in product sub-categories not working properly

[Nick Hatzinikolaou]

Hello, I found an issue with the way the search works on the administration.

Let's say we have two categories "Test White" and "Test Black".

When you add a new product you go to the Product Categories field and start typing the category name, especially useful if you have hundreds of categories.

If those where top level categories then typing "Test Wh" will produce results. If they where sub-categories though then typing "Test Wh" will return no results!

At first I thought is as an issue with white spaces or searching two words, but it works fine on the top level...

Is there any fix for this issue?

Thanks
