Hi Anithya, There is a mapping file for MappingCharFilterFactory that behaves the same as ASCIIFoldingFilterFactory: mapping-FoldToASCII.txt, located in Solr's example conf/ directory in Solr 3.1+. You can rename and then edit this file to map "ä" to "ae", " ü" to "ue", etc. (look for "WITH DIAERESIS" to quickly find characters with umlauts in the mapping file). There is a commented-out example of using MappingCharFilterFactory in Solr's example schema.xml.
If you are using Solr 1.4.X, you can download the mapping-FoldToASCII.txt file here (from the 3.x source tree): http://svn.apache.org/repos/asf/lucene/dev/trunk/solr/example/solr/conf/mapping-FoldToASCII.txt Please consider donating your work back to Solr if you decide to go this route.
