ISO-8859-1 The query that doesn't work looks like "+_area:skåne". With Zend_Lucene I'm getting no matches, but if I run this query in Luke I ge...

I've been tasked with seeting up a search service on an eCommerce site. Currently, it uses full text indexing on sql server, which isn't ideal, as it's slow, and not all that flexible.
