Anytime someone does a search I get this error and no results.  I notice portal ID and UserID are -1 if that matters not sure.  I have tried reindexing, clearing cash, deleting whats in the search folder and again reindexing with scheduler and admin re-index feature.

Seems to be Sequence contains more than one matching element is the clue for GetSearchDocuments

How and where do I repair this feature as I have been digging in it for some time now.  Thank you.
