One of the most valuable things I did when I started out (way back in the Lucene-only days) was try to answer _one_ question every so often. Even if someone else beat me to the punch, I benefitted from the research. And the rest of the time I discovered things I never knew about Solr/Lucene!
I think one of the most valuable lessons was "Somebody's probably run into this before, I wonder what _they_ did?" ;) Best, Erick On Thu, Jun 2, 2016 at 9:46 PM, MaryJo Sminkey <mjsmin...@gmail.com> wrote: > Well thanks for asking the question because I had no idea what Andrew > posted was even possible... and I most definitely will be using that > myself!
