If I do a search on my site for 'mary blige' on my site http://www.musicimport.biz/Default.aspx, it will not find any item but if I search for 'blige mary' then it will find the items.
Is there something that I have to change?

You might have to put mary blige in the keywords to get the search to pull it up- the basic search does only title and keywords, and evidently only if the terms are in a certain order.
