I have a problem searching for someone in SharePoint 2010. In my organization there is a person whose surname is "Uña" (nail in english) but cannot be found in search. When I write his surname in search textbox returns 0 results. When I user another usual surname like "López" returns a lot of results. If I search for a complete name + surname returns only one result.
Search service are properly configured and there are a lot of more things like documents to search for.
UPDATE - 01/18/2012
I realized that this happens when the search is on "k" parameter instead of using a metadata property that find the person correctly. For example, if the query string is like 'k=uña' don't return any result but when is like 'k=personname:"uña"' returns some results.
My suspect is that the search engine thinks that when someone write "uña" means "una" and, in Spanish, this word is an article so there isn't a word to search for because articles are so common. I made some test using other words with "ñ" and return correct results.
Does anybody know how can I add some words to avoid these comparation?
