Hi, I'm using Solr 6.5.1, and I'm facing the issue of incorrect ngroup count after I have group it by signature field.
Usually, the number of records returned is more than what is shown in the ngroup. For example, I may get a ngroup of 22, but there are 25 records being returned. Below is the part of solrconfig.xml that does the grouping. <updateRequestProcessorChain name="dedupe"> <processor class= "solr.processor.SignatureUpdateProcessorFactory"> <bool name="enabled">true </bool> <str name="signatureField">signature</str> <bool name= "overwriteDupes">false</bool> <str name="fields">content</str> <str name= "signatureClass">solr.processor.Lookup3Signature</str> </processor> < processor class="solr.DistributedUpdateProcessorFactory" /> <processor class ="solr.LogUpdateProcessorFactory" /> <processor class= "solr.RunUpdateProcessorFactory" /> </updateRequestProcessorChain> This is where I set the grouping to true in the requestHandler <str name="group">true</str> <str name="group.field">signature</str> <str name="group.main">true</str> <!--<str name="group.ngroups">true</str>--> < str name="group.cache.percent">100</str> What could be the issue that causes this? Regards, Edwin
