Solr 6.4.2

[Daniel Miller]

For those trying Solr - version 6.4.2 fixed a number of bugs in the 
6.4.x series.  Speed is incredible.  If you haven't tried it - I 
strongly recommend it!
And, using the included installation script (with Solr) combined with my 
schema - installation was painless.  I'm now running in single core mode 
without issues (running in cloud mode with a single core seemed silly 
anyway).
