How to set up and validate locally

Note: Advanced Search must be installed and enabled in gdk. gdk reconfigure needs to be run to pull the new indexer down (i think)

1. add DEBUG to the env variables sent over the the indexer if you want to see multi line output (this is what will happen when an error occurs)

2. edit any repository file for any project
3. verify that the indexer output show up in the elasticsearch.log
