Filter lists + FilterMultiValue for multiple columns.

Hi,

I want to filter a list using URL Querying using the FilterName and FilterMultiValue.

For example i put this at the end of the AllItems.aspx? 

"&FilterName="Title"&FilterMultiValue=*"Printer"

Works perfectly.

Now i want to filter it twice (on another list column). So i do

"&FilterName="Title"&FilterMultiValue="Printer"&FilterName="Brand"&FilterMultiValue="HP"

But the second filter never gets applied. Anybody know how i should be doing it?
