Hi Otis, There is no error in console nor in log file. I'm using Solr-4.0. The External file name is external_rankingField.txt and exist is directory "C:\solr-4.0.0\example\solr\collection1\data\external_rankingField.txt"
External file should work as well because when I issue query "sort=sqrt(rankingField)+desc" or "sort=sqrt(rankingField)+asc" or "sort=sqrt(rankingField)+desc" Things will change accordingly. By the way, I first try external field according document here http://lucidworks.lucidimagination.com/display/solr/Working+with+External+Files+and+Processes "Format of the External File The file itself is located in Solr's index directory, which by default is $SOLR_HOME/data/index. The name of the file should beexternal_*fieldname* or external_*fieldname*.*. For the example above, then, the file could be named external_entryRankFile orexternal_entryRankFile.txt. " But actually the external file should put in $SOLR_HOME/data/ Floyd 2012/11/20 Otis Gospodnetic <otis.gospodne...@gmail.com> > Hi, > > Do you see any errors? > Which version of Solr? > What does debugQuery=true say? > Are you sure your file with ranks is being used?
