When executing an advanced search, some fields appear as available for selection, and some fields...

In Archer, not every field created in an application is automatically indexed for searching. Within the Field Properties (General Tab), there is a checkbox titled "Searchable." As taught in Archer Administration II , if this option is unchecked, the field will be invisible to the Advanced Search tool.

This is often done by administrators to improve system performance or to hide technical "helper" fields (like those used in calculations or DDEs) that have no business value for end-user reporting. If a field is missing from the "Available" list in the search builder, the administrator must go back to the Application Builder, edit the field's properties, and ensure the "Searchable" checkbox is enabled. Option B (Key Field) would actually make the field more prominent, and Options C and D do not control the visibility of fields within the Advanced Search interface.
