Hi Steve, thanks for the reply. I did not understand which file do I need to rename? I'm working on Solr 1.4. The file in examples/solr/conf directory is mapping-ISOLatin1Accent.txt. The Schema.xml has the following commented entry. <charFilter class="solr.MappingCharFilterFactory" mapping="mapping-ISOLatin1Accent.txt"/>
Do I need to replace mapping-ISOLatin1Accent.txt with http://svn.apache.org/repos/asf/lucene/dev/trunk/solr/example/solr/conf/mapping-FoldToASCII.txt mapping-FoldToASCII.txt and change the charFilter mapping to <charFilter class="solr.MappingCharFilterFactory" mapping="mapping-FoldToASCII.txt"/> ? -- View this message in context: http://lucene.472066.n3.nabble.com/How-to-search-for-special-chars-like-a-from-ae-tp2444921p2447888.html Sent from the Solr - User mailing list archive at Nabble.com.
