Hello, i managed to fix the problem. I'm using Solr 7.5.0. My problem was that in the server logs i got "This Indexschema is not mutable" (i did not know about the logs folder, so i just found out 5 minutes ago). I fixed it by modifying solrconfig.xml to
<updateRequestProcessorChain name="add-unknown-fields-to-the-schema" default="${update.autoCreateFields:<b>false*}" processor="uuid,remove-blank,field-name-mutating,parse-boolean,parse-long,parse-double,parse-date,add-schema-fields"> <processor class="solr.LogUpdateProcessorFactory"/> <processor class="solr.DistributedUpdateProcessorFactory"/> <processor class="solr.RunUpdateProcessorFactory"/> </updateRequestProcessorChain> Since then the indexing is done correctly. I even got the blob fields indexation working now ! Thanks for your reply, everything is fixed for now. -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
