Hi, Did you attach your chain to a UpdateRequestHandler?
You can do it by adding &update.chain=langid to the URL or defining it in a defaults section as follows <lst name="defaults"> <str name="update.chain">langid</str> </lst> On Tuesday, April 29, 2014 3:18 PM, Victor Pascual <vic...@mobilemediacontent.com> wrote: Dear all, I'm a new user of Solr. I've managed to index a bunch of documents (in fact, they are tweets) and everything works quite smoothly. Nevertheless it looks like Solr doesn't detect the language of my documents nor remove stopwords accordingly so I can extract the most frequent terms. I've added this piece of XML to my solrconfig.xml as well as the Tika lib jars. <updateRequestProcessorChain name="langid"> <processor class="org.apache.solr.update.processor.LangDetectLanguageIdentifierUpdateProcessorFactory"> <lst name="defaults"> <str name="langid.fl">text</str> <str name="langid.langField">lang</str> </lst> </processor> <processor class="solr.LogUpdateProcessorFactory" /> <processor class="solr.RunUpdateProcessorFactory" /> </updateRequestProcessorChain> There is no error in the tomcat log file, so I have no clue of why this isn't working. Any hint on how to solve this problem will be much appreciated!
