Help Screen - Advanced Search option

Hi,
For any help ( advanced search) option, gives only Beginning with option.
For example, for advanced search of Item, it gives only beginning with option, is it possible to add some more control like Item Name, UOM, Selling Price and so on?
Please guide how to do.
Thanks
Jakir
