Backend related product search

[dnlvsci]

Is there any way to show up to 10 related product on backend search? When I want to serach related product on custom filed tab I can see only ten hit.
Example: I have 20 skirts and 10 T-shirts. When I want to relate product for T-shirt I'm typeing "skirt" word in the search form. After that I can see 10 hit, but this is not enought for me.

Anyone can help me? :$
