Re: chaning schema
Erik: Is this a Tomcat-specific issue? Because I regularly delete just the data/index directory on my Windows box running Jetty without any problems. (3_x and trunk) Mostly want to know because I just encouraged someone to just delete the index dir based on my experience...

Re: chaning schema
Well, the nice thing is that I have an Amazon based dev server, and it's AMI stored. So if I screw something up, I just throw away that server and get a fresh one all configured and full of dev data and BAM back to where I was. So I'll try it again with the -rf flags. I did shut down the server and I am using Tomcat. Dennis Gearon Signature Warning It is always a good idea to learn from your own mistakes.

Re: chaning schema
It could be related Tomcat. I've had inconsistent experiences there too, I _thought_ I could delete just the contents of the data/ directory, but at some point I realized that wasn't working, confusing me as to whether I was remembering correctly that deleting just the contents ever worked. At the moment, on my setup, I definitely need to delete the whole data/ directory . At one point I switched my setup from jetty to tomcat, but at about the same point I switched my setup from single core to multi-core too. So it could be a multi-core thing too (which seems somewhat more likely than jetty vs tomcat making a difference). Or it could be something completely else that none of us know, I just report my limited observations from experience. :) Jonathan On 2/3/2011 8:17 AM, Erick Erickson wrote: Erik: Is this a Tomcat-specific issue?

Re: chaning schema
From http://wiki.apache.org/solr/DataImportHandler#Commands The handler exposes all its API as http requests . The following are the possible operations [..] clean : (default 'true'). Tells whether to clean up the index before the indexing is started so, no need for an (additional) delete *:* or?

Re: chaning schema
the trick is, you have to remove the data/ directory, not just the data/index subdirectory. and of course then restart Solr. or delete *:*?commit=true, depending on what's the best fit for your ops.
