ICUTransformFilterFactory

[Jochen Lienhard <li...@ub.uni-freiburg.de>]

Hello,

we have a problem with some special characters: for example æ


We are using the ICUTranformFilterFactory for indexing and searching.

We have some documents with "urianae" and with "urianæ"

If I search "urainae" so I find only the versions with "urianae" but not 
the "urianæ"
Only if I search "urainae*" I find both versions.

Is it possible (perhaps by special IDs in the 
ICUTransformFilterFactory), so that I can find all without an asterisk?

Greetings from Germany

Jochen Lienhard

Why don't you use MappingCharFilter?
