Search Query

Search Query

Hi,

I have a database and one of my categories is what phones people have. So I have a list of loads of phone makes. I would like to pull out people on the database who don't have iPhones and Blackberry's just leaving everything else. 

Is there a way to put that into the search query with the 'Not contains' or 'Is not' section? I have tried it but it wont work. 

Is there a special way to separate them and make it work? Like........ Is not ---- "Blackberrry", "iPhone" 

Many thanks

Gill
