Search removes/ignores diacritics (e.g åäö)


I'm on CMS 11.10.5, Find 13.0.5.

Using For(query) in all fields or selected fields with no configuration overrides seems to match content regardless of diacritics in the query, e.g. "Miljo" matches content named "Miljö". However when using a specific filter such as Filter(x => x.Name.Matches(query)) the exact letters are matched (as expected/wanted). I've tried specifying the language, analyzer etc and I haven't found any information about special characters, diacritics, invariant strings in the documentation or source code. Is this behavior locked or can it be modified?

Edit: The actual indexed document shows the letters intact (åäö).

Hi Bob,

Thank you - interestingly enough I hadn't, however I have already tried supplying the appropriate language branch to the client when searching as the example on that page indicates, without success.

To clarify, the way EPiServer documentation states it should work is actually working correctly i.e. on the resulting side of things:

Given a page with the name "Startsida":


Returns 1 result


Returns 0 results (correct)

However, given a page with the name "Miljö" (with a diacritic in it, but searching without the diacritic):


Returns 1 result


Returns 1 result (this is my issue, should return 0 results)

I have a similar problem on my side with the french language and Find.

Is there any update on this issue ? Is possible to have the bug number to check if it was fixed ?

Thank you!
