Uwe, Would you mind to provide a few details about your case? I wonder about number of bigterms and other stats as well at 'author' field (ant other most expensive facets). It looks like log rows:
Sep 13, 2011 2:51:53 PM org.apache.solr.request.UnInvertedField uninvert INFO: UnInverted multi-valued field {*field=nomejornal*,memSize=827108,tindexSize=40,time=16,phase1=4,*nTerms=15,bigTerms=0*,termInstances=750,uses=0} Those heavy requests, do they find more than half of docs, eg hits>maxdoc/2 ? Thanks for your input!
