SharePoint 2010: Problematic Search and default normalization.

Hello. I use Search Core Results web part to find users by LastName. My custom Search Core result does not work with Å charaters (returns both Å and A). Problems seems to be that SharePoint 2010 normalizes Å to A which should be fixed. But is it possible to 'educate' sharepoint search to know more characters.

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This is an issue of enabling Search Diacritics to use the characters instead of treating them as accents.

In MOSS 2007 this was enabled using STSADM as such;

However there's no Powershell mapping for this in 2010 as things have seemingly changed...

Indeed searching for the property on Technet yields this;

"This class is obsolete now. Please use SearchServiceApplication and SearchServiceApplicationProxy instead."

I haven't touched this side of things on 2010, and can find no reference to diacritics with these two classes.

What I did turn up was this, which I suggest you look into;
