Hi Bruna
Typical problems with diacritic searches comes from the ausence of an specific 
filterm ISOLatin1AccentFilter in the DSPace configuration of the Lucene engine. 
 You must try to change DSAnalyzer.java adding two lines:

import org.apache.lucene.analysis.ISOLatin1AccentFilter;
result = new ISOLatin1AccentFilter(result);

You will also need to recompile DSPACE AND rebuilt the indexes

best luck

Hi folks,

We are using DSpace as the base for our objetc repository at UDESC (Joinville, Brazil). But, now, we notticed a problem with search with diacritics and special characters (acents, etc).

For example: in portuguese the correct spelling for the word critic is "crítico". In the DSpace Documentation we have the information that the search ignores this signs, however, if we search for "critico" without acent, we don't have the same results when we use "crítico".

It doesn't work for searching Author, Title, Subjects... and doesn't work for XMLUI neither JSPUI.

Thanks for the help!
