[TYPO3-commerce] Products search

[Cray Flatline]

I need to implement two things in my wathces site:

1. Search of the product with certain ordernumber. So on the site will 
be simple text field and  button "search". When user write there some 
ordernumber, it has to show product with this ordernumber. Can I 
implement it?

2. I need to make search within products by the sertain attributes. For 
example i need to find all watches with:
    a) some brand
    b) some brand and steel case and steel (or leather) bracelet
    c) all watches with price from __ to __

Have anybody any suggestions for it? (:
