thank you for your answer.i read it and i use this filter in my schema.xml in solr:
<filter class="solr.PorterStemFilterFactory"/> but this filter doesn't understand all words with their suffix and prefix. this means when i search 'rain' solr doesn't show me any document that have 'rainy'. -- View this message in context: http://lucene.472066.n3.nabble.com/how-index-words-with-their-perfix-in-solr-tp3542300p3544319.html Sent from the Solr - User mailing list archive at Nabble.com.
