Not with ICUFoldingFilter, but with the MappingCharFilter. There you can supply a mapping file and skip baseletter mappings for the users' native language, because in their own language, they know the correct spelling ... most of the time ... sometimes.
This does really help with multiple languages and you lose the convenience of ICUFoldingFilter.

External e-mail. Hi, I'm looking at using ICUFoldingFilter for a customer, to fold e.g. Genéve to Geneve and thus get better recall. However, for some common Norwegian words, the folding makes them clash with super-common words so it becomes impossible to find exactly what you want. I imagined if ICUFoldingFilter had a preserverOriginal=true option, then it could leave the original word in the index on the same position, and an exact match for "Genéve" would score better than the normalized one. But this filter does not support this. Have anyone found a workaround for this, except from duplicating all content in different fields with different analysis and search across them with different weights? Jan
