Hi Peter,
On two separate DNN 4.9 DMX 5 portals, both setup with MS Indexing Service, the module Tools|Search function is not returning any results. Neither the Simple Search, nor the advanced search, even on just a title. Selecting whole repository does not help.
The DNN integrated search does return results, as is the query tool in MS Indexing Service.
I've checked my Search settings and they are correct. I remember there were search problems in earlier versions of DMX 4, but you corrected them.
Let me know what else I can provide or if you need portal access to troubleshoot.
