Major Description
The crawl script makes it a bit challenging to use an indexer that isn't Solr. For instance, when I want to use the indexer-elastic plugin I still need to call the crawler script with a fake Solr URL otherwise it will skip the indexing step all together.
bin/crawl urls/ crawl/ "http://fakeurl.com:9200" 1
It would be nice to keep configuration for the Solr indexer in the conf files (to mirror the elastic search indexer conf and others) and to make the indexing parameter simply toggle whether indexing does or doesn't occur instead of also trying to configure the indexer at the same time.
