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.
I presume your analyzer normalized accented characters? Which analyzer is that?
You will need to employ some form of character normalization on wildcard queries too.

Thanks

Hi
I get an unexpected behavior when use wildcards in my queries. I use a EnglishAnalyzer developed with SnowballAnalyzer. version 1.1_dev from Lucene in Action lib.
Analysis case:
When use wildcards in the middle of one word, the word in not analyzed.
Examples:
QueryParser qp = new QueryParser("body", analyzer); Query q = qp.parse("ex?mple"); String strq = q.toString(); assertEquals("body:ex?mpl", strq); //FAIL strq == body:ex?mple
qp = new QueryParser("body", analyzer); q = qp.parse("ex*ple"); strq = q.toString(); assertEquals("body:ex*pl", strq); //FAIL strq == body:ex*ple
With this behavior, the search does not find any document.
Bye Ernesto.
