Hello, fellow DNNers

I promise I've resorted to both Google searches and this forum, but I'm not finding an item that quite matches the issue I'm wrestling with at the moment.  To be fair, part of the problem might be I am not using the DNN specific terminology when I search.

I've put the Search Result Module into a page, configured it to search pages-- nothing exotic.

When I conduct any kind of search (simply by term, or with tags, doesn't matter) it goes through the motions of an AJAX powered search, but says there are no search results.

When I use "Inspect Console" to peek behind the scenes of a search, I'm getting this:

http://example.com/DesktopModules/internalservices... 500 (Internal Server Error)      jquery.min.js?cdv=18:5 

send     jquery.min.js?cdv=18:5


b.extend.ajax     jquery.min.js?cdv=18:5


dnn.searchResult.doSearch    dnn.searchresult.js?cdv=18:223


dnn.searchResult.searchInput.$.dnnSearchBox.searchFunction   dnn.searchresult.js?cdv=18:353


(anonymous function)

I've verified that the primary alias is set in my Site Settings-- a suggestion I found in one of my previous Google searches.  The URL doesn't get an parameters added to it (a different suggestion from a different search), but since it's AJAX powered, I am not really expecting it to, either.

I don't have access to the hosting machine, only to the actual DNN instance itself-- so I can't look in the Event Viewer Application Log for more details, for instance.

Is there some other way I can track this down?
