I know about numFound. That's where the issue is. On a complex query that takes mins I think there would be a major chunk of that spent in calculating "numFound" whereas I don't need it. Let's say I just need first 100 docs and then want SOLR to STOP looking further to populate the "numFound".
Let's say I just don't want SOLR to return me numFound. Is that possible? Also would it really help on the performance? In MySQL you can simply stop it to look further a certain count for "total count" and that gives a considerable improvement for complex queries but that's not an inverted index so not sure how it works in SOLR...
