Hi, I don't seem to be able to get the merge core feature to work with Solr 7.2.1. I'm using the srcCore parameter method documented at https://lucene.apache.org/solr/guide/6_6/coreadmin-api.html#CoreAdminAPI-MERGEINDEXES
I am making the following GET HTTP call using a browser: http://localhost:8991/solr/admin/cores?action=mergeindexes&core=mcol&srcCore=col1&srcCore=col2 In the call above the following cores are referenced: merged core name: mcol core 1 name : fc1 core 2 name : fc1 All 3 cores preexist. The response content I get is : { "responseHeader":{ "status":0, "QTime":57}} I see the following in the logs: 747532 [qtp2028017635-17] INFO org.apache.solr.servlet.HttpSolrCall - [admin] webapp=null path=/admin/cores params={core=mcx&action=mergeindexes&srcCore=fcl1&srcCore=fc2} status=400 QTime=2 756577 [qtp2028017635-18] INFO org.apache.solr.update.DirectUpdateHandler2 - start mergeIndexes{NRTCachingDirectory(MMapDirectory@C:\collections\fc1\data\index lockFactory=org.apache.lucene.store.SingleInstanceLockFactory@7c53c896; maxCacheMB=48.0 maxMergeSizeMB=4.0),NRTCachingDirectory(MMapDirectory@C:\collections\fc2\data\index lockFactory=org.apache.lucene.store.SingleInstanceLockFactory@3e2255a5; maxCacheMB=48.0 maxMergeSizeMB=4.0)} 756602 [qtp2028017635-18] INFO org.apache.solr.update.DirectUpdateHandler2 - end_mergeIndexes But the number of docs in the merged core do not increase post merge operation. Search for keywords that exist in the core1 do not return results with merged core. Am I missing something? Best regards, Piyush.
