Should "a" match "ä" in ferret?

Ruby Apps Ferret

Hi all,

I have indexed a huge amount of data with text from several european
languages. In the index are values like Georg Friedrich Händel.

I would like a search phrase like “Georg Friedrich Handel” to find
records with the real spelling of Händel but it doesn’t seem to work.

Can anyone give me an idea of what I need to do to make this happen. A
bit lost here and can’t seem to find anything on google to help out. I
have an idea that it might be a locale issue but not sure.

Thanks,

Chad.

I’m a 100% sure this has been asked before in this list. But I know
it’s not exactly trivial to search for it.

I’d say, give it a try on the archives.

Chad,

you should use a mapping filter to transform special characters like
german umlauts into its ascii counterpiece.

take a look out this analyzer, maybe it helps …

To achieve this, simply replace all occurences of ‘ä’ by ‘a’ in both
indexed content and queries.
MappingFilter [1] is your friend :slight_smile:

Cheers,
