"Lucene/Solr doesn't actually delete documents when you delete them, it just marks them as deleted. I'm pretty sure that the difference between docCount and maxDoc is deleted documents. Maybe I don't understand what I'm talking about, but that is the best I can come up with. "
Thanks Shawn, yes, that is correct and I was aware of it. I was curious of another difference : I think we confirmed that docCount is local to the field ( thanks Yonik for that) so : docCount(index,field1)= # of documents in the index that currently have value(s) for field1 My question is : maxDocs(index,field1)= max # of documents in the index that had value(s) for field1 OR maxDocs(index)= max # of documents that appeared in the index ( field independent) Regards ----- --------------- Alessandro Benedetti Search Consultant, R&D Software Engineer, Director Sease Ltd. - www.sease.io -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
