: My gut says the difference in assignment of docids has to do with how the : FileListEntityProcessor<http://wiki.apache.org/solr/DataImportHandler#FileListEntityProcessor>
docids just represent the order documents are added to the index. if you use DIH with FileListEntityProcessor to create one doc per file then the order of the documents will (if i remember correctly) corrispond tothe order of the files returned by the OS, which may vary. even if the files are ordered consitently by modification date: 1) the modification date of these files on your machines might be different; the graunlarity of file modification dates supported by the filesystem or file io layer in the JVM on each machine might be different -- causing two files to appera to have identical mod times on one machine, but different mod times on the other machine. -Hoss
