look for filters that use the ICU4J library

Hi, we use a modified ISOLatin1AccentFilter bit to replace German accents by ae, oe, ue and so on for that purpose. In the code you will see a switch for the characters. You need to change it from case '\u00E4' : // small ä output[outputPos++] = 'a'; output[outputPos++] = 'e'; break; To something like this case '\u00E4' : // small ä output[outputPos++] = 'a'; break; for the characters you want to replace.

I'm trying to find a way to convert German Umlauts written as 'ue', 'ae', etc to folded form 'u', 'a' and so on. This is done by GermanAnalyzer (and German2StemFilter used by it), but unfortunately it also does stemming which is very undesired in my case. Is there any other filter that can do only the 'ua' -> 'u' conversion? 2. Is there any filter that does 'ü' -> 'ue' (NOT 'u') conversion? What I'm trying to achieve is that word "über" should be found in the index whenever the user searches for " über" or "ueber" , but NOT "uber".
