Starting with SOLR

[Ken Kirby]

Hi Folks - I'm struggling with getting started using SOLR. I've a new SOLR 4.6.0 install and have indexed the example documents provided in the example configuration.

I think I have the BuildIndex command created in a similar way to that specified on the wiki page related to using SOLR, and I think that I've seen, in comments here, that Lucene 4.6.0 is compatible with SemanticVectors 5.4 - however, unfortunately I'm finding the following error when running BuildIndex

C:\sment\clas_srv\sv>java -cp semanticvectors-5.4.jar;lucene-core-4.6.0.jar pitt.search.semanticvectors.BuildIndex -contentsfields title,text -docidfield id -luceneindexpath C:\sment\clas_srv\solr\example\solr\collection1\data\index

If you may have crossed this bridge, any help would be greatly appreciated.

Thanks

PS - Dominic, I am VERY eagerly waiting for the copy of "Geometry and Meaning" that I just got on Amazon - your sample chapter was awesome! With SemanticVectors, Geometry and Meaning, OpenSkyMap, etc, you seem to be a remarkable person - thanks so much for sharing!
