Hi Hoss, > Did you perhaps forget to include RunUpdateProcessorFactory at the end?
What is that? ;-) I had copied the config from http://wiki.apache.org/solr/UpdateRequestProcessor but removed the lines I thought I did not need. :-( I've changed my configuration, and this is now WORKING (4.0-ALPHA): <updateRequestProcessorChain name="emptyFieldChain"> <processor class="solr.RemoveBlankFieldUpdateProcessorFactory" /> <processor class="solr.LogUpdateProcessorFactory" /> <processor class="solr.RunUpdateProcessorFactory" /> </updateRequestProcessorChain> <requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler"> <lst name="defaults"> <str name="update.chain">emptyFieldChain</str> <str name="config">data-config.xml</str> <str name="clean">true</str> <str name="commit">true</str> <str name="optimize">true</str> </lst> </requestHandler> LogUpdateProcessorFactory and RunUpdateProcessorFactory were missing. Once those are in place, DIH does commit and optimize and the documents are visible immediately to the WebGUI and the Searchers. It would be nice to have those two factories mentioned as required (or when you would want them in the config) in the example solrconfig.xml and the wiki: https://builds.apache.org/job/Solr-trunk/ws/checkout/solr/example/solr/collection1/conf/solrconfig.xml and http://wiki.apache.org/solr/UpdateRequestProcessor Javadoc of RunUpdateProcessorFactory doesn't tell me so much. I can have a look at the source and try to write something wise on the wiki about it. :-D Thanks Hoss! Chantal I'm going to update the other thread with how to handle empty number fields with either 3.6.1 or 4.0 http://lucene.472066.n3.nabble.com/NumberFormatException-while-indexing-TextField-with-LengthFilter-and-then-copying-to-tfloat-td3996250.html
