Subject Re[2]: Analyzer don't work with wildcard queries, snowball analyzer.
Date Fri, 01 Apr 2005 13:09:18 GMT
Hello Erik,

Since wilcard queries are not analyzed, how can we deal with accents ?
For instance (in french) a query like "ingé*" will not match documents containing
"ingénieur" but the query "inge*" will.

Thanks
