Hi Jeff
Lars here. I am afraid the missing result property is because you are using the Wildcard license and not a full license. The Wildcard license does not support custom properties in the search results. I know FirstName is a standard property and it should actually have been supported. The Wildcard license only supports the following result properties:
author, accountname, contentclas, contenttype, birthday, department, fax, homephone, interests, jobtitle, memberof, memberships, mobilephone, path, officenumber, responsibilities, size, sitename, sitetitle, skills, username, website, workaddress, workcity, workcountry, workemail, workphone, workstate, workzip, write
The Ontolica Wildcard edition checks the configured result properties against this list and ignores all not in it. Ultimately, this is a bug in the product. FirstName need to be added to this list to fix your problem.
But I am afraid I cannot fix it for you as I have moved on to new ventures. Please try and contact the Ontolica support team on mssupport[at]surfray.com and ask for a fix.
Cheers
Lars Fastrup
