: - I think that the use of log files is discouraged, but i don't know if i : can modify solr settings to log to a server (via rmi or http) : - Don't want to drop down solr response performance
discouraged by who? ... having aseperate process tail your log file and build an index that way is the simplest way to do this without impact Solr's performace ... alternately you could write a custom LogHandler that sends the data anywhere you want (so you never need a log file) but that would require some non-trivial asynch code in your LogHandler to keep the budiling of your new idex from affecting hte performace (log calls are synchronous) -Hoss
