Subject Re: multilanguage + howto search in all languages?
Date Thu, 29 Jan 2009 00:47:55 GMT
I'm not entirely sure about the fine points, but consider the
filters that are available that fold all the diacritics into their
low-ascii equivalents. Perhaps using that filter at *both* index
and search time on the English index would do the trick.

In your example, both would be 'munchen'. Straight English
would be unaffected by the filter, but any German words with
diacritics that crept in would be folded into their low-ascii
"equivalents". This would also work at index time, just in case
you indexed English text that had some German words.

NOTE: My experience is more on the Lucene side than the SOLR
side, but I'm sure the filters are available.
