Subject RE: How to search for special chars like ä from ae?
Date Mon, 07 Feb 2011 20:54:47 GMT
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.

Good luck,
Steve
