Hi, I am trying to use the IndexMergeTool to merge two indexes that are indexed in different collections into one. Both collections have the same fields, and are using Parent-Child Block-Join.
When I tried to run the following command as stated from the Solr Wiki https://cwiki.apache.org/confluence/display/solr/Merging+Indexes java -cp "C:/solr/server/solr-webapp/webapp/WEB-INF/lib/lucene-core-6.5.1.jar":"C:solr/server/solr-webapp/webapp/WEB-INF/lib/lucene-misc-6.5.1.jar" org/apache/lucene/misc/IndexMergeTool C:/solr/collectionMerge_shard1_replica1/data/index C:/solr/collection1_shard1_replica1/data/index C:/solr/collection2_shard1_replica1/data/index I get the following error: Error: Could not find or load main class org.apache.lucene.misc.IndexMergeTool What could be causing the error? This is done on Solr 6.5.1 Regards, Edwin
