- This is just a quick first pass at a guide for getting Nutch running with Solr. I'm sure there are better ways of doing some/all of it, but I'm not aware of them. By all means, please do correct/update this if someone has a better idea. Many thanks to [[http://variogram.com||Brian Whitman at Variogr.am]] and [[http://blog.foofactory.fi||Sami Siren at FooFactory]] for all the help! You guys saved me a lot of time! :)

I'm posting it under Nutch rather than Solr on the presumption that people are more likely to be learning/using Solr first, then come here looking to combine it with Nutch. I'm going to skip over doing command by command for right now. I'm running/building on Ubuntu 7.10 using Java 1.6.0_05. I'm assuming that the Solr trunk code is checked out into solr-trunk and Nutch trunk code is checked out into nutch-trunk.
