While it is possible to set up the search module to search by specific fields, it would be great to be able to 'search everything EXCEPT field 1 or field 5' for example. This would enable searches to be of all content but still managing to exclude fields such as EMAIL where someone has added their email to a submission field. At present you can search everything and get lists of posts where a specific username or email address is present in a hidden field on the original form. Not good for data protection.
