Hello!

I work with a large number of DNN sites in Sweden and has found a problem that I now supposed to find the root of.

The problem is that the internal search function in DNN does not index words containing Swedish characters (åäö). For example, the word Nässjö can not be found.

Is there a setting you can do to include special characters?

Have you found a solution to this?
I have the same sort of problem. I did get so far as to see that the Swedish characters are getting indexed in the database.

You can test to see this by using the sql below in the host/sql.

select top 100 * from searchword

But the words do not come up in the search results :-(

This is a bug. Accented search term is encoded by HtmlEcode function (SearchResults.ascx.vb, line 292) and then searched in database. Unsuccessfully - of course. Without html encoding returns searching terms with accented characters expected results.

Any tips about how to get around this? It is a major problem for a Swedish site.

I found this thread incidentally and realized that this problem will affect my sites too. Therefore I looked at the code and found problematic location in file SearchResult.ascx.vb on line 292. The code on this line looks as follows:

_SearchQuery = 
HttpContext.Current.Server.HtmlEncode(objSecurity.InputFilter(Request.Params("Search").ToString, 
PortalSecurity.FilterFlag.NoScripting Or 
PortalSecurity.FilterFlag.NoMarkup))

I have no idea why should be input parameter string html encoded. The result is that accented characters are encoded, i.e. mangled. If you remove the HtmlEncode function call then the unchanged input search string can eventually be positively compared against the key from the data table. I tested this with dnn version 5.6.1

Regarding the tip: change of code is presumable the only way.
