Huh, the NGramFilterFactory itself isn't listed on the the analyzers wiki at: http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters
That wiki page seems to be protected to certain users only. Anyone know if there's a way to send a 'patch' to the maintainers for the wiki, or if there's a process for getting editing privileges on that page? I'd like to help out by adding documentation when I come accross it.
