I use jetty that comes with solr. I use solr's dedupe
<updateRequestProcessorChain name="dedupe"> <processor class="solr.processor.SignatureUpdateProcessorFactory"> <bool name="enabled">true</bool> <str name="signatureField">id</str> <bool name="overwriteDupes">true</bool> <str name="fields">url</str> <str name="signatureClass">solr.processor.Lookup3Signature</str> </processor> <processor class="solr.LogUpdateProcessorFactory" /> <processor class="solr.RunUpdateProcessorFactory" /> </updateRequestProcessorChain> and because of this id is not url itself but its encoded signature. I see solrclean uses url to delete a document. Is it possible that the issue is because of this mismatch? Thanks.
