Hi; There were two issues about adding preserveOriginal capability to EdgeNGramFilterFactory and I've made a patch about it. You can check and test it from here: https://issues.apache.org/jira/browse/SOLR-5152 This is the related issue that can be marked as duplicated: https://issues.apache.org/jira/browse/SOLR-5332
Thanks; Furkan KAMACI
