We had our portal at DNN 5.0.1 and search was not working.
I am not sure where, but I found some information about how Search was not working in this version of DNN, so I opted to upgrade to 5.2.1, the current latest release.

After the upgrade however, Search still acts exactly the same way? You enter a search term, click the search button, and the page simply refreshes - nothing else. No search results, no blank search results, just the same page you were already viewing, just a flicker as it refreshes.

Help?
Thanks!

Thanks Sebastian - but I guess I am not sure what you are referring to here?? 

Thanks Sebastian -

So if this is a DNN5 installation, and when you click the search button, the page you are on simply refreshes, and (seemingly) nothing happens, where does this point to as an issue? 

We have never put any Search Results modules on any of our pages. I have always assumed when you searched, the app would take over and display the results for you, not that we would have to setup a separate search results page on our own? 

What am I missing? What are you referring to when you state "search results page is not properly configured (e.g. permissions)"? 
Sorry if I am being dense - I feel as though I a just missing something entirely here.

Thanks again!
