Is it possible when using a custom link to run an advanced search to have the search look at only specified fields within the object?  For instance, I have a link on the Account detail page that runs an advanced search on Accounts and it uses a custom field value as the search criteria. The search returns Account records that have the value in any number of fields, thus usually returning more records than I am interested in.  I want to have the search return only records that have the specified value in a field or fields to be specified in the custom link.  Can this be done this way or in another way?
